Run fault codes to check for sensor and electronic faults. Have a compression test done to check for gasket-head and valve problems.

Your catalytic converter is plugged up,  If you check the exhaust output at the tailpipe you will find it restricted.
Let me know if I  can assist further.

Have you checked for spark on all 8 plugs? Unplug the exhaust side coil pack and run the engine. Does it run on all 4 cylinders?

I have a 1992 chevy lumina 3.4L engine and I had to replace the starter. I am putting the starter in and I need to know how many wires to hook up? My dad thinks there's a wire missing.


Dual overhead cam (euro)?

the small purple wire will go to the small terminal on the starter. there should be 3-4 other wires that attached to the large terminal of the starter.

most likely it is an engine miss fire when hot, the smell is the catalytic converter overheating because of the miss fire, if you fix the miss fire the smell will go away, try replacing the spark plugs and plug wires, and see if the problem dose'nt go away.....good luck

1990 Lumina running roung, power loss rough idle


On the chevy v6 engines it real comon to have intake leaks.I would try spraing carb cleaner around the intake while the car is running and see if it changes the way it runs.If it does that is your problem.If the intake has a leak it will **** extra air in and cause a missfire.
