try checking youre timing
Spark Plugs need replaced Bad or Old Distributor or even a weak fuel pump, or old fuel filter.
When you replaced the plugs, did you check the compression? Did any of the plugs look different than the others? Low compression in one cylinder can cause misfiring. But then, so can a faulty distributor cap.
BEst bet is the alternator... some tell tale signs are wierd gauge reads and it dies while driving it...
Check the fuel pump, rotor, and distributor cap.
replace the plugs,wires,distributor cap,rotor and air filter.
Spark plugs, distributor cap, and distributor rotor should be replaced. Ignition coil should be checked for corrosion at the post. Clean or replace as needed. Spark plug wires should be inspected for corrosion. Clean or replace as needed. PCV valve should be cleaned. Fuel filter should be relaced. Air filter should be inspected and replaced if needed. Oil and filter should be changed if applicable.
Make sure your plug wires are connected tightly to the correct spot on the distributor and the plugs.
Hi, There can be many things that could be happening. Your spark plugs could be loose or bad, your distributor and rotor could be bad, your fuel filter could be clogged, your air filter could be clogged, these are just some starting p[oints. Good luck. Steve H.
Is it a brand new distributor ? If not then replace the module and pick-up coil in the distributor that you have.
check the harmonic balancer
you could check the fuel pressure and fuel filter.
Assuming the fuel filter has also been replaced, a bad distributor cap and or wires and spark plugs could do that also.
