When trying accelerate my car stumbles or thumps real bad recently ...
someone said could be fuel filter, another said fuel injectors , another said fuel pump & filter
Any ideas?
Mine started the exact same thing today, im thinking its fuel too, odd cause the filter's somewhat new (less than 6 months old), im leaning personally towards fuel pump, which sucks cause i just filled up yesterday.
i filled mine up Friday morning i still have about 3/4 tank
and a fuel pump is like $290 and a bitch to fix having to drop the tank out n all that.
tomorrow im putting a new fuel filter in and maybe take the fuel injectors out and clean them
and another cause could be bad spark plugs?
Check your fuel pressure, KO/EO, KO/ER, and 2000RPMs.
Post your results.
