Question about 1993 GMC Sonoma Club

1 Answer

Have a 1993 Gmc Sonoma 4.3 CPI, idles rough and spits and sutters on acceleration, clears up after hitting about 25mph but if i coast a while and give it gas it runs rough again. Smell excessive exhaust fumes like it's overloading with fuel and it's only getting about 8 to 10 mpg. Any ideas anyone?
