1988 ford ranger is miss firing

MikeyFord3 · Jan 12, 2009

I just bought a ford ranger 2.9 liter. The truck seems to be missfiring, it idles fine and runs fine when im at a constant rpm, but when i accelerate it seems to miss fire. Does anyone know anything that it could be?

What has been done?? tune up?? fuel filter??

check grounds and for vacuum leaks

ok will do..
some people were saying it could be a head gasket how would i know if it was?

white exhuast smoke after it warms up, might smell like coolant too
"snot" under the oil filler cap after running for a long time
milky oil on dipstick and the oil in the pan when you drain it you can tell
sudsy oil
low compression on one or more cylinders (20% of the compression of the other cylinders or more)

if you change out the plugs just do a quick compression test and it will tell you alot about whats goin on.

could be ignition module too or spark related
