I have a 86 IROC I put a 350 in, all sensors have been changed but one, the ESC module, I have been haveing a problem with the car dieing when putting it in gear, could the ESC module be the problem?

 

yes, but it's probably not your problem...is your ses light on? if so scan it for trouble codes, and if it isn't on right now, scan it anyway could have a stored code. If there is a code, record it, then look up what the code means. There is a chart on the main page here under the FAQ's i believe. Check all your plug wires and your plugs first..check your base timing by disconnecting the est connector on the passanger side at the firewall. Do a search on setting the timing and you will find lots of info on how to do it. Good luck and report back..

 

The codes are 36, 42,
I have been haveing problems with the MAF burn off for a while now (new relay, and plug) but the code keep coming up, still working on it. I am going to a search and see what else to look into.

Code 42 is new and it is the ESC module, so I will replace it with the one for the 350, so I hope it will take care of that code.

 

If you need one, I have a used but working one for 10 shipped. Its for a 87-89 350 TPI

 

Throwing parts at the problem might fix it, but it'll cost more money and take longer then properly diagnosing the problem. Stop taking shots in the dark and get a Helm/GM shop manual for your year vehical and follow the troubleshooting charts.

You problem sounds more like an IAC or TCC issue then anything to do with the knock sensor. You could disconnect the knock sensor completely and it would still run.

 

The ESC is for a 305 not a 350, could the code 42 also be for the knock sensor too? I bought a sensor kit from TPIparts.net so the only sensor not new is the ESC.

 

a 305 and 350 are differant part numbers.

 

They're different numbers, but if you swap a 350 into a 305 car and use the 305 knock sensor it will still run without throwing codes.

 

The knock sensor and E-prom are for the 350, but the ESC is not, its for the 305. Could this combo be a problem as far as runing right?

Thanks for all the help guys.

 

Right off hand I would say that it shouldn't matter, however, it certainly wouldn't hurt to upgrade to the correct sensor. I still don't think it'll fix the problem you're trying to resolve.

 

Thanks for your honesty in this matter.

 

My exh. started to rattle real bad today, could this trigger the knock sensor and be part of my problem?

Thanks again guys

 

Anyone????

 

TTT

 

let me get this straight!

did you just ask if an exaust rattle set off the knock sensor.

sorry dude to chuckle

listen to some of the senior members on this board like drew when he tells you to get a helms manual for your ride if you intend to work on it yourself instead of taking it to a shop

believe me it is sound bulletproof advise

thanks again for the funny
