Hey what's up everyone. I'm new to third gen camaros. This is my first american muscle car and so far I'm loving it! I just recently bought a red 92 RS 5.0 with 130k on the odo. Its been very well kept. I have a few questions. first I've never owned a vehicle with tbi, the idle is steady at about 650rpm but the car seems to vibrate quite a bit is this normal idle? Second after I shut the car off a few seconds later I hear a hissing sound from under the drivers side this is where the fuel fil ter is located correct? And lastly when shifting into second gear there's a thud in the rear what links or arms can cause this? Any input would be great thanks.

 

Welcome aboard and welcome to the world of 3rd gens. I believe the hissing you hear is normal, mine does the same thing. Has something to do with evaporative emissions I believe. The rough idle could just be dirty injectors needing some cleaner run though them or an air filter change. The "thud"???? Possibly a broken tranny mount.

 

Hissing is likely no problem, either the fuel pump, or the A/C equilizing the pressure. Clunk could be anything, tranny mount is a good place to start.

But no, there should be no vibration at idle. 305 TBI idles very smooth, something is wrong. Could be anything, but I would check ignition first, it's one of those things that people seem to neglect.

 

Jtsk and eseibel67 thanks for your help and pointing me in the right direction! Will definitely check the plugs and rest of the ignition system.

 

Yes welcome aboard the thirdgen ship.
