i think the scanner im using is the wrong one the innova i was on another site where someone had the same problem with that brand and had the same codes and not addressing the real DTC codes. so can anyone recommend a good scanner. besides a cable im just thinking of getting a 95 1.5 obd2 pig tail and swapping them. i just want my car running right. i have ocd lol and this is driving me insane. some of the codes are for 3.8L from what that scanner is showing and come to find out it does not do all 94-95 camaros just the v6's so that may be the issue

 

I am also using an innova scanner 3120b. It does seem kinda weird so many codes pop up.

 

I did some research and found a link where a guy tried using the innova 3120b on a 94 lt1 and it wouldn't work. He called innova and they told him that when the scanner prompted for the 8th digit of VIN to enter in J instead of P.

I just went out to my car and tried this and it seems to have worked.This time i only got 4 codes
Codes 12,16,22,35

 

wow thanks very very much i have to try it now.
i also found a broken ground in the car on the steering column bracket and a broken pick and yellow wire so need to fix them as well once again thanks and i will try it now

 

code 12 ? what is tht cant find info on it

 

tried your tip and no dtc codes with the vin change, but still have a check engine light and found the main wire loom under the steering column a ground, pink which im thinking is ignition and red which is a 12v source. so could this be my problem for the voltage issue i have been having? or is my optispark having issues with voltage?

 

code 12 apparantly means all is well, how is your car running?

 

well mine is running rich it seems like and the check engine light is still on even when i used the scanner and vin j code says no dtc codes detected.

 

i have the alternator off the car when it was tested but still was running rough before

 

I am stumped...one day i can go out and crank the car and it runs alright just a lil rough,then next day go out and crank it only to have it start and run really rough(sounds like it cammed and missing) but yet last week all was fine, my car only has 150 000km on it.

I'd like to know if these scanners are any good as well. When entering the correct info into the scanner it comes up with the same 8 codes every time. But when i use the scanner with VIN j intead of p i only get 4 codes.code 35 is invalid,another is 12 which means all systems pass and is supposed to always come up from what i understand,and if you only see code 12 supposedly all is well.also got a code 16 and 22.

I am trying to get a hold of a actron scanner and see if it will give the same codes.

 

yea this problem is driving me nuts as well i hope i can figure it out. if you find anything let me know as i will do the same. i just might pull the whole engine harness to inspect for shorts i cant visually see

 

well i wonder is battery cables a factor the person that had it before me put negative wires on positive instead of buying the oem cable.

 

So still no progress on car tested fuel pressure everything checked out okay, pulled the fuel rails to check for leaky injectors and none were leaking but i'm gonna take em in to get them cleaned anyway as they are kinda dirty. I also took back that crappy innova scanner and got my money back and ordered one of these http://www.aldlcable.com/sc/details.asp?item=aldlobd1u
I am going to hook it up to my laptop and scan with datamaster to see what codes i get.
I also replaced the fuel filter.
Once i get my injectors cleaned and back on and get the cable in the mail i will scan my car and post my results.

 

ok let me know this problem is killing me

 

all that work and i over looked the obvious it all was over a bad connection in the MaF had to pull it apart and fix the connection sensor now runs like a top and no check engine light. i guess its keep it simple stupid lol

 

your car is no longer throwing any codes?

 

if all those codes are gone from a bad connection in the maf...i hope it something that simple with my car

 

no more codes and cleared up still need to drive it to get the excess fuel deposits remaining in the system. but yea weird but it was something simple i overlooked

 

Hey I’m having the same codes pop up and was wondering where to start!! My car is cammed with LT headers stall. With a lil rear end work
