A few things i can think of as this happen to me on my ford , somebody left a rag in exhaust pipe before refitting , funnily enough this has happened , but i think if vacume hoses are incorrectly fitted this can cause this also , also check timing , also the exhaust gas return pipe may have fault at the inlet manifold regulator , which is where the pipe comes of the inlet manifold , check that also , sometime that valve is at fault .


hope this helps , good luck

Replace timing belts crank sensor runs rough at idle an exaust gets cherry red


This could be several things. One is obstructed CAT. The most common cause though is the engine is running so rich it is dumping unburned fuel into the exhaust. This could be a bad injector sticking exhaust valve, constant misfire etc. Don't run it like this or you will end up with a pile of charcoal and steel where your car is supposed to be.

2001 Caravan has red hot catalytic converter and #4 misfire error code.


Engine is way too rich. You will burn that car up. Unburned fuel is getting into the CAT and igniting. Check the injectors.

Catalytic converter stopped up. Pipes got red hot. Replaced Cat. Conv. car runs good, then started random misfires, pipes got red hot again. What is exhaust part that is downstream of Cat. Conv. could it...


If the exhaust system was plugged the engine wont run, normally. It will start and idle until the back pressure is such that it can't take in more air/fuel mixture and then stall.

After the converter, there may be a resonator, and then the muffler. Is any exhaust flowing out of the tail pipe? You might try hooking up a scanner and see what your oxygen sensor(s) is/are doing.
Also, scan the MAF(mass air flow) sensor assembly.
Sound like the engine can't breathe, and its getting to much fuel.

When warm runs rough sets knock sensor code will hardly idle turn front cat cherry red car sat for a year put new gas in it when cold runs great


If the cat is cherry red as you say it is I would check the firing order or timing they may have crossed plug wires this will cause the exhaust manifolds to get red hot and glow let me know if this heled you and good luck.It definitely sound to be timing related or crossed wires.

1990 Buick Century 3.3L Check Engine Light comes on, stalls.


Need to check for fault codes. Possibly a faulty sensor causing the fuel system to run rich or lean.
