Problem Description and Possible Solution
Misfires under load (acceleration) can be caused by the valve cover gaskets leaking oil into the spark plug wells shorting the spark plugs to the cylinder head. New spark plug wires will be needed and the valve cover needs to be resealed.

loss of Acelebration. when I get about 40/45 miles an hour its misfiring and shaking I've changed the wires and plugs and the valve cover gasket but it still doing it don't know what to do
Check engine light came on and started blinking and then it started to sputter. Checked it out with the computer and came back three codes PO400, PO404 and PO406. Cylinder six is misfiring.
When vehicle comes to a stop and idles in drive the rpms start to jump and sometimes the car stalls out, but starts back up . Car drives fine while its accelerating just when it comes to a stop it can stall out
Once the engine warms up, it begins to stall, then doesn't start again till cooler. One out of one misfire shows up on cylinder 6,which has small amounts of oil at the base of the plug. After restarting, loss of acceleration and eventually stalling occurs. The engine is hot, but doesn't read high, and all fluids check normal. No vacuum leaks either. Plugs, wires have been replaced, all plugs sparkplhg. I'm seeing a minor leak behind the lower back to the left of the timing case.
Valve cover s leaking oil into plug wells shorting out spark plugs
Car keeps dying on me! runs great in morning come home from work cant make it home.
Misfire in the 3rd cylinder, oil found in the spark plug wells, oil leak from the valve cover. I took the car to the shop and they will replace the valve gasket for $400, hoping that could solve the problem
My car starts jerking after I'm going 40 but only when I try to keep the gas peddle at a constant speed
Cylinder 6 misfires causing check engine light to appear. Replaced plugs & boot (on #6). Hope this works.
I replaced the distriuter cap now I don't know what plug goes where in the right order.
Car has misfire in 3rd cylinder also has oil in 3rd cylinder around spark plug
I have had a problem with my car since it died and had a cam sensor code. I replaced the distributor and got it started again. But now it had no power and is throwing misfire codes. I have checked the timing and set it at 12 btdc and still low power. Any suggestions?
runs good I drive it everyday but she's talking on the floor it's like it's cutting out of gas
Cyl#3 not firing consistantly, rough idle,
excess oil burning,
When I start my car it sputters and the rpm goes up and engine light blinks then stops the blinks again
Check engine light flashing
Codes p0325 and p0303
the car idles and drives roughly
Changed plug wires and plugs, cap and rotor, and ignition coil
My next step is the valve cover gaskets and seals and knonk sensor
Also possible that the catalytic converter is going out
idk Can't take it anymore
I was just doing some routine maintanance changing the plug wires and spark plugs and when i got to the back 3 spark plugs i noticed the first one was dripping with oil and oil was puddle in where the spark plug goes. The job calls for 3 and a half hours labor. Does not sound fun.
