Hard to say if it is related to exhaust or ignition timing if you take the car for a long drive and take a look at your exhaust manifold and if it is glowing cherry it could be related to your exhaust or timing a freind of mine had the same thing happen and the cataliytic was plugged and the timing was out. the cat was probly plugged due to the timing being out.I would also check the timing.It could also be an injector problem,fuel filter,or some other area of the fuel system these problems are hard to diagnose without actual hand on so just check those areas and let me know of any other symptoms hope this helps?

SOURCE: bogs down at high acceleration
Sounds like a plugged catylic convertor, GM has a Special Policy adjustment that covers the catylic convertors for 10 years or 120,000 miles (190,000 km), whichever occurs first, from the date the vehicle was originally placed in service, regardless of ownership. This is for 2001-2002 models with 3.4L or 3.8L engines. If you have a 3.8L engine you want to get this fixed soon, I have seen people drive these things so long with the convertor plugged that they melt a hole in the plastic intake plenum where the EGR port comes into the intake behind the throttle body.

if it has a converter on it.....it may be stopped up, but before you replace it have the fuel pump checked, as it may not be getting enough gas at higher rpms. It will start and idle fine, but starve out when you press the pedal. Have you changed the fuel filter?That will cause the same problem.....

Replace the TFI module. Ford back in 1986 thur 1993 had problems like the one you wrote about. TFI module gets hot and shuts car or truck off then when it cools sometmies starts and sometimes not.

I think it might have to do with the throttle body butterfly, in the air intake, which usually accumulates dirt and hampers its function. Clean this out and see how it goes then.
