hey guys been a member of third gen for a few years now but first time poster! as i didnt have a camaro up until now!

it is a 1987 IROC-Z 350tpi

just as title says:
had codes 13-o2 senor, 21-tps, 43-electronic spark control!
car runs sluggish and has a rich smell to it!

has anyone had these codes all at the same time?
dont really want to spend the money and find out it is something else!

thanks for the help in advanced

 

I would start by checking the TPS

thanks i will try that!

 

This might sound crazy, but I had a similar situation last year with multi codes. I remember the "43" because I had to look it up. I disconnected the battery for a minute then hooked it back up. This clears the codes in the computer. Hooked it back up, ran the car ... no codes since then.

Also got strange codes right after I bought my car because I wanted to put "the best" gas in and was using the highest octane (thinking it would run better). Read an article on TGO not to do that because our systems are designed for the 83 octane. Changing gas got rid of knock sensor errors and it runs better.

"car runs sluggish and has a rich smell to it!"

Mine did the same thing until I adjusted the timing.

 

ok well i changed oil on the camaro last nite and layin there i just happened to look up and see that the plugs are rusted and dont look like the have been changed in a quite a few years! any advice as to changing them without stripping them? i am pissed off bout that as the kid that i got it from said they changed them!
changing them should help with the slugish problem! i hope!

i also happened to look around on the passenger side of car as it has an exhust leak and i noticed a wire just hanging there! the clip end was all melted! i found the sensor that it goes to but the clip on that end is broke to! now i am not sure what sensor what to order!
it is located on the right side of the engine just under the exhust manifold if anyone know what that sensor is?

thanks in advanced!

 

Hello chevyman87!!

Do you have A/C?

That should be the connector for the secondary cooling fan temp switch, on an A/C equiped car!!

If you don't have A/C, that temp switch is basically redundant, and as a result shouldn't affect anything!!

 

yes car has a/c but i was told that is a knock sensor idk if that is true though!

 

Hello chevyman87!!

The knock sensor is down on the block, and not on the cylinder head!!

 

ok thanks!
