[QUOTE="deadpool1, post: 441229, member: 21229"] The cause of actual misfire, for sure at WOT, not just idle , not just fast right foot for only 3 seconds ,but misfires all the time cold or hot or both this is a mostly MACRO answer: (this time and a no guess parts and throw them answer) [LIST] [*]the engine is actually bad, compression test fails, or say coolant seen on spark tips.? [*]Spark is bad, a full 60k tune up is not throwing parts it is listed in the 60k service points, cap/rotor/hv wire sets/ & plugs. [*]EFI is bad. (the fueling side) injectors bad , 1/2 clogged or leaking. fuel pressure wrong. at idle and or WOT . [*]MAP sensor bad. making ECU compute fueling wrong. for the vacuum hose to it is bad, clogged or cracked. [*]ECT bad tells ECU that you live in Alaska, (reads wrong ohms for 72 degree temps before first start in the AM) FSm covers it. [*]Any wiring bad to any of the above that has wires. if you still get DTC 24 the TPS is still failing for bad wires. [/LIST] there are tests for each possible case using tools, meters (DMM) , fuel pressure gauge, compression gauge, etc) more causes are CKP bad, (crank sensor is flaky , intermittent,)a gain wires. the CMP in the Distributor , is inject to cam sync sensor, and if set wrong injections will be timed wrong and misfire it can. The Distributor pulled then put back in now is TIMED wrong. every time. it must be done correctly ,by the book FSM (free) 95,,,,2.5L (usa spec car) wires bad means the wire or the pins or corrosion see, cut wires smashed, wrecked, etc. or insultation missing and now shorts other wrong things even to metal of the body or the engine, this is called damaged wires. electrics 101 stuff I am not saying this is the only list, just top causes, (majors) [/QUOTE]
