SOURCE: Hard start, rough idle, some black smoke, engine service light on

A scan for trouble codes may point you in the right direction quickly, rather than hit & miss, with replacing parts. Some of the autoparts stores will scan for free, and your right where you need to be to get the right part at the same time.

3.9 ltr V-6 running very rich, acts like it is choking out when trying to accelerate and blows black smoke. Is this a fuel problem?


Yes, the engine is being overfuled if blowing black smoke. Possible internal leak of fuel pressure regulator. Possible sticking/stuck EGR valve. Possible computer supplying more fuel due to a sensor supplying false information. A scan tool will be required to determine if one or more sensors is supplying erratic info

What color is the smoke? White smoke is oil burning, black is fuel. There are a dozen things that could cause the symptoms you describe. Faulty fuel pump, dirty injectors, ignition system fault, cracked cylinder head, bad fuel, faulty engine sensor (MAP, OXY) etc. Really need to find a mechanic who can look at it in person.

Idles rough and smokes when first stated


Worn valve guides allow oil to drain into the cylinders, causes blue smoke, fouled plugs will idle rough.
Coolant in the cylinders from a blown head gasket will cause white smoke.

Not saying this for sure, but I had the same problem, and i have a 1994 xr7 V6 3.8 L , and all u need to do is set the idle down manually because your computer could have seen that the injector was stuck open, and tried to turn up idle to keep up with the amount of fuel being pumped, worth a shot :P
