I’m going to replace the spark plugs and wires tonight. What else should I go after?
so far:What you now describe is the engine not firing properly, worse under load. What have you done or checked in the last couple of days? MIL on? Recent fill-up just before it happened (still on the same tank of gas??). Could be fuel system (or fuel) related or ignition,
you can say that again.lot of possibilities.
so far:
checked all wiring
drained/refilled tranny
checked plugs/wires
same tank of gas. fill up at the same gas station i always go to.
on tap:
replace plugs/wires
replace cap/rotor
drop tranny pan
replace fuel filter
you can say that again.![]()
wingnutter:
Can you give more data on what is actually happening? "Shudder" generally refers to the tranny slipping then grabbing hard in quick succession; like a bumpa bumpa bumpa; A roughness on acceleration like the engine is missing badly, then causing a generalized vibration, is a different animal.
