I've ohm checked the distributor (and checked gap and no oil inside), cold start injector, EGR VSV, ISC and plug wires. I vacuum checked the EGR valve and looked for vacuum leaks. Also looked for bad ground. All are good. Fuel pressure was within spec.
Last night, I replaced the distributor and cap (rotor and wires only 1 yr old) and strangely the power is mostly back. Especially on take off and it will climb a hill without much problem. The miss is still there but seems to be showing up around 40mph. The lack of power is not as bad as before. I can actually pull out in traffic but there is a bucking when accelerating.
Before all of this happened, the car ran good but would vibrate when stopped at a light and in drive. Sometimes worse than others.
Could a fuel pump cause these issues? The pressure was good and it's never left me stranded.
Any ideas? Help!
have the same problem?
