Symptoms after cam swap...
Rough idle. sometimes it idles good, other times it will almost stutter and die...when it idles smooth it sits around 800rpm's. When it doesnt it is close to 500 and will sometimes drop to 200-300. Especially at stoplights.
When it doesnt die, it seems like it cant find its idle. It will move around between 300 and 1000 up and down and wont sit still.
It also seems like I am losing a little bit of power, however I have not gotten on it completely because I am trying to break in the new head gaskets...
I have an intake bolt missing. It is the one where the alternator bracket sits, but I got rid of that beracket. The bolt NEVER bolted into that hole since I got the car, and I do not have another bolt to fit it. I know it is not stripped, but would that be the problem???
Oil Pressure sits around 20 at idle, 60 driving...that is about normal right?
CEL is on as well, and I have not gotten to the auto zone to check what its on for, but it came on the SECOND I started the car. Might have something to do with it. I am about to go get it checked...what do you guys think tho about the idle?
a single pattern cam on a 112lsa like the ZZ409 should have no problem holding a smooth idle. my 224/230 cam didn't even idle lower than 700~rpm even with a stock tune
have you reset the pcm since your poor running condition?
The codes were TPS and Crank Position Sensor. I replaced the TPS and it solved the idle problems. The CPS is on order now but is a quick swap. Acceleration is not up to par tho IMO.
The codes were P0127 (TPS), P0335, P0336, both 335 and 336 said the exact same thing...CPS. What would be the symptoms if my CPS is out???

Hes mentally el stupido.
I came here for help and advice and I thank those people who gave me that. But your critisizm over a mistake that is done and over with is NOT what I needed.
I'm glad your a perfect mechanic in a forum and all...it means alot, really it does, but NOTHING YOU SAID EVER helped me with my situation or provided any insight. If you have such a ******* WEALTH of knowledge then I would think you would be smart enough to SHARE IT instead of being a moron and running me into the ground about this.
