Question about 1995 Chevrolet Cavalier
You could pull apart the exhaust anywhere convenient in front of the converter, and see if car runs like it can finally breathe.
The temperature gun adrian is referring to is a hand held infrared temp. senser. point it or hold close to exhaust pipe. Temperature after converter should be about 100 degrees hotter than temp. before converter. That shows converter is good and working, getting rid of the unburnt hydrocarbons in the exhaust, and not clogged.

Temp gun. rear of converter should be hotter than front of converter.power loss is also a way of knowing your converter is plugged. car seams to be under stress load sound when running..

engine starts fine but if cold it revs up good. once warmed up is when the troble starts. The exhaust tone is very quite or none, the exhaust comes out of the pipe real seady no pulseing or put put. The xhaust seems very hot and the converter seems very hot you pull out and the car picks up then slows down. Take a front oxagen senser out to create a leak leave it plugged in and tye it up someway so it won't get damaged while you drive. If the car drives much better the exhaust is cloogged. if you put a pressure gauge on the hole where the oxagen senser was screwed in and run the motor, ( just ram the hose against it ) if the gauge reads any more than 5 lbs. even with the engine revved up your clogged. Good is negitive pressure revved up

1. Check bulbs and/or fuses and replace if needed
2. Possible that the brake light switch down on pedal is bad but, if your like is like mine it would be your turn signal/hazard signal switch. Therefore:
3. Replace turn signal/hazard signal switch. GM part price for this is around $500. Can find some, non GM part for around $225. Or do what I did and go to local junk yard/auto parts yard. Found the part I needed for $80, off a car that had only 48,000 miles on it. For dealer to put on is around $150. Did it myself by following this excellent thread. All of my "screws" were torx, not as described in the thread, but everything else was great! www.clubgp.com/cgi-asp/mods.asp?modid=141. Taking to Dealer would have cost around $700. Thanks to Clayton Auto Parts and this thread with pictures, it cost me $80 and about 2 hours time. email@example.com
