- 98 explorer xlt
i own a 98 explorer xlt v6 4.0l 182k miles. The problem started with a misfire here and there and loss of power but it still got up and went and check engine light went on. one morning i tried to start it and had to crank it 4 maybe 5 times and its been like this every time i try to start it. once it starts it idles very low maybe 600 rpm and when i give it gas it tries to die. when driven it hardly moves, you could floor it and it would go 20mph tops and slowly increase speed, also stutters when given gas unless you press the pedal very slowly. also hear pops from intake like misfires.
i took it to auto-zone for a diagnostic read and they told me i had a few codes . i replaced everything that it said. one injector , coil pack, new ngk plugs, and new spark plug wires, fuel filter, and fuel pressure regulator. once all that was installed there was no difference and the check engine light remained on. so i had the idea it might be the MAF even though it was not throwing a code for it. i changed the MAF and it did turn the check engine light off but no change in performance.
any ideas on what it might be the cause? maybe internal problem? i dont hear knocking. fuel pump works . at times when warmed up in park it can be reved high no problem, but then it just goes back to stuttering and in drive it has no get up and go. it barely moves
