Well the rockers are one of the things I found that didnt look "normal". This happened in less that 5000 miles. We pulled a buddies valve covers off his car and his looked nothing like mine with alot more miles ... so I questioned it... their is definatly a problem with the car and I am looking into what I found to see what is causing it.... I have a popping out the exhaust and car idles like **** as well as the HP is down on the car... I never said the rockers were causing my problems, but maybe that was a sign on where the problem was... Valve train purrs like a kitten on passanger side of car but sounds like a sewing machine on the drivers side.... you tell me, where would you start looking???? I found stuff that people tell me "isn't right" or "shouldn't be that way"......

A few people now say that is a common thing with the LS1's for the rockers to twist.... and I can deal with that. I already bought a set of aftermarket rockers to fix that problem. But there has to be a reason they twist like they do....

Reguardless... all I want is my car back running right again, and I dont care what caused it right now, just want it fixed. If I didnt truely know there was a problem with it, wouldnt be pissing away all kinds of money trying to fix it... Id be spending my money on more "GO FAST PARTS"... so I'm not nuts!

 

Have you checked for any damadged wires?
Could possibly be the Crank position sensor wires. They run close to the pass side header and get damadged failey easily from the heat.

Could also be Plug wires.

I have changed plug wires, spark plugs numerous times, had injectors checked, ohmed coil packs, compression test, leak down test performed by a shop and tested fuel pressure... this problem started at beginning of the year... car ran good for 3 months... winter hit... started car and ran it for min. of 1/2 hour once a week driving when i can over the winter... brought car out in the spring and there the problem was... idle ruff, sound of like a missfire out the exhaust and a noticably loud ticking from the drivers side head area...


Where is this crank sensor located to check for wire damage??? I have seen a sensor in the oil pan, but dont remember seeing another. Thanks

 

Look on the pass side fender well. There is a bundle that runs down towards the starter. It contains 02sensor/starter/Crank pos sensor wires.

To get a good look at the wires you will need to Lift the car up and remove the starter. The Crank position sensor harness plugs in just above the starter.
If those wires are damadged at all it can cause the problems you are describing.

I may be totally off but I think I gave ya one more thing to check lol.

Brad

 

Well if you are correct, that would be great... if that was the problem.... it wouldnt throw a code, or strms and ltrms wouldnt be affected???? Cause none of those things happened.... What does the crank position sensor actually do?

Thanks for all the help!

 

Since we dont have a Distributor it tells the PCM where the crank is to help with Ignition timing.
The Cam position sensor is more important for this but it uses both signals.

When mine was screwed up I did get a p0101 code a few times (MAF) but not consistantly.
Mine would Shut off at WOT and backfire. Sometimes it would just breakup at high rpm. And It did have some problems at Idle as well.

If you don't find a problem with those wires, check all grounds and make sure no other wires are damadged.

E-mail me the info at justasix@hotmail.com

 

How about this... you come on by and I will show you every email and post I have printed out, as well as concrete evidence of edit files and parts... the car is apart so you can check that out too... The info I have is way too much to email. I will be the first to admit when I'm wrong, but I will not back down when I'm right. You want to know the truth, just let me know when... Cuz ya know what...everyone that posted in the thread was a speed inc friend and never listened to me... well i would side with my friends too. But not once did I get ignorant as I was called a liar, automotive hypocondriact, and dishonest, and an ******* by them numerous times. AND NOT ONCE WAS I DISHONEST...and WHY??? What would I gain by lieing to them??? They need to know whats EXACTLY going on to find and fix the problem RIGHT??? So how would I benefit???? Just stop and think about that for a second. They couldnt run any tests with me there to see the results, so should I think that about them???


Let me know when ya want to stop by...

 

This post is here to help aid in finding and fixing my problem with my car and I would like to keep it on track.... Thanks

 

Hey bro,

May sound stupid, but I didn't read the whole thread....did you check or replace all your springs? I had a broken roller rocker/ and spring.....car just died.....

I had a dealership fix the arm and broken spring since i was an hour from home.....

When i finally got new springs from RPM I found another broken spring when we swapped the old ones (thanks again Wayne).....we couldn't see it until we pulled them....it was broken very low in the head seat.....

If your rocker arms look messed up or bent that could be a sign....I know you are fed up and frustrated......it will all work out.



P.S. I never got any codes or anything when my rocker arm and spring broke.....

 

I'll stop by. Call me and give me your number and address. 630-531-5666. Andy.

 

Ok. Andy, Glad your willing to stop by and see for your own eyes, but what will this accomplish for me? What are your motives??? Are you going to go back and post your findings??? I doubt that very much being that speed built your car and tunned it for you and any help from you to me will result in you probably loosing your good friendship with speed inc... SO, tell me how this is going to benefit me and I will call you ASAP! Sorry if I sound defensive, but you are friends with them and I dont think youd cross them to help me.


BTW- Do you have LS1 Edit???

 

Next Phase.... I changed all the rockers with a NEW set and checked all the springs and none were broke. Thanks for the idea!

 

This might not be your answer but it was mine. Do you have an A/f gauge?
My car was stumbling and missing and all the same symtoms you were mentioning, I also did all the things you mentioned, plugs wires, coil packs, injectors all that. Finally after 2 months I traced down the problem. It was the main purple wire that comes off the gauge that you use to tap into your o2 sensor had gotten burned and freyed. Never threw any o2 code. I replaced the wire coming from the gauge and the o2 sensor. Fixed

 

Thanks for the reply transaman00, but I have no gauges, and if one of those wires were burnt or something, i would imagine i would throw a SES light or something if it were the case, but checking things on a tech 2 (by a speed shop) and autotap by myself, everything seems to be normal other than IAC counts are lower than usual, but im sure that has to do with the car idling like crap....

Keep em comming!!!! Thanks!

 

It didn't throw a code for me either as far as anything o2 related. After about a 1/2 weeks of doing it, it finally threw a code it was a misfire code #6 cylinder. But there was nothing wrong with that cylinder. Like I said I replaced everything that would even cause a misfire before I even got the misfire code and it was that burnt o2 wire the whole time. BTW this later happened on bank 1 with my other gauge. Came up misfire on cylinder 1 and it was that sides o2. Also if your IAC counts are low and you are having a poor idle why not replace the IAC? Turn your A/C on and see if your RPM's drop w/out bumping back up if so replace the IAC.

 

With A/C on they jump up... so I would think it isn't the IAC, as well as I cleaned that and the MAF Sensor with electronics cleaner, and no difference...

I had SLP Headers and the wires that run along side to the crank sensor dont seem to have a problem... There was the heat shield from the SLP kit as well as the stock heat tape on there, and the plastic wire holder covering all the wires and nothing looks burnt or damaged....

This car must be posessed!!!!

 

Have you tried Exorcism??

 

You asked for help and offered for someone to come over and check it out. I'm willing. I have nothing to gain by this other than helping and maybe learning something. Anyone that knows me will confirm that I will call a spade a spade. I'm not looking to bust your *****, it's not worth my time. You seem at witts end, I'm offering to help. If you want, call me, if not, no problem . BTW I have HP Tuner. Andy.

 

BTW, I had a extra set of stock rockers and purches with 5000 miles on them. I was going to let you try them.
