Ok heres my issue i started doing more bodywork this week went to start the car it will not idle i have to rev it up to 2 gees and keep it there as doing so i noticed a smell and the exhaust got really hot all the way down to tips does anyone know what would cause it

seems like the idle problem and exhaust problem have to be linked seeing as i started the car 3 weeks ago it was fine
someone said that there could be critters in the exhaust which will not let it idle ..

 

if it aint idleing on its own, its probly too rich and hence why you need to give it more throttle (more air) to keep it running. Running rich and at 2000 rpms will quickly heat up the exhaust. Also, whats the engine timing? too much retard on timing and abit rich on fuel will heat up pipes ALOT

 

Possibly high backpressure. take off the exhaust, and check it for flow. Possibly do have some critter in there, and you were smelling... well... cooked critter?

 

When the cat. converter on my daughters car plugged it behaved the same.


...if its not a squirrel.

 

if your converter is cloged up or no good it will caue it to over heat and glow red like that check your cadilac converter

 

I will check the timing tomorrow also will drop the exhaust how would I know if the cats shot is there a way to physically see..

 

Yeah, but you have to take the catalytic converter out. A bright light at one end should be visible from the other end. Or just run it with the front of the converter unhooked If your neighbors aren't to close.

 

OK ill check exhaust tomorrow is there a way to adjust the richness im more of a carburator man the 92 Camaro is a RS with the TBI 305

 

If it all of the sudden started doing this then unplug the CTS near the thermostat

I recently had to repair a LO5 with super rich startup problems. Turns out when the CTS goes bad it either gives no signal or max signal of -70C or something very cold. The ECM compensates by adding fuel for this arctic air coming in. Since its not really arctic air it just drowns on all the extra fuel

 

Ok i dropped the exhaust all the way up to the cat it still would not idle i pulled the cat still the same thing still have to goose the gas to keep it running i cant check the timing seeing as it does not idle the battery was weak and died so i have to recharge or buy a battery and start looking at the suggestions on the cts

 

Check your timing by loosening the distributor, and having a helper keep the car running from inside of the car, and adjust and slowly let off the throttle to have it idle. Also check for any vacuum leaks, that could cause a no-idle issue.

 

sorry dude but i have to single you out because this kills me...

Cadillac is an AUTO MAKER, not an Emissions device, and having one on yer car sure as hell doest make it a cadillac.

the emissions device is called a CATALYTIC converter, because of the face that it is a Catalyst

 

Check in the Tech/General engine section

Unhooked exhaust rules out the cat. To test the CTS unplug it and fire it up. Same problems means the CTS is not the culprit

If the timing is way off it can run lean and cause the exhaust to get VERY hot. Check with a timing light rather than attempting adjustments blindly. Be sure to disconnect the base timing connector near the HVAC box if you do reset the dist

 

Ok one question were is the cts located im pretty new to the 92 camaro..

 

Ok heres the list of whats has been done.

1: dropped the exhaust removed cat
2: Pulled the CTS sensor tried that same thing car still does not idle
3: installed new fuel filter
4: installed new TPS sensor
5: Replaced the IAC
6: Set the timing as stated to 0 and brought it up by 2
7: cleaned Throttle body and added hightest fuel

Now the exhaust does not get hot but car does not stay idle and runs alittle rough i will change plugs wires and distro cap fuel pump this week..

 

went to go start on the car today and guess what I turned the key and nothing brand new battery and brand new starter i tested the battery it has a full charge im guessing the starter went from trying to get it running right yesterday
going to pull it out and bring it back to advanced auto..

 

Ok after all this fumbling around with the above the starter was not the issue seems my VATS is messed up the security light is on that would explaine the raunchy running 305 issues i have been having going to try to do the VATS jumper config using some info i found here on this site..

 

VATS kills the starter and fuel control

If it runs at all its not a VATS issue

 

I had the car running before this as stated above that was the reason for looking in to the VATS..
I tried the vats bypass and nothing what i get is when i turn the key
the electric fan spins i hear a click near the driver firewall and nothing is there a starter relay switch im missing..

 

Ok heres a quick update on what i have done
1: bypassed Vats
2: tested neutral safty switch
3: replaced starter "had Advanced auto test before leaving there store"
4: replaced Battery
5: checked all connectors on coil and distro

still when turning key i hear 1 click on the driverside firewall and the radiator fan spins no clicking at all to the starter ..
