I have 98 that runs fine when cold. Starts fine, drives fine and accelerates fine. After it warms up it starts fine, idles fine but when you go to give it gas it stumbles. Let off the gas it regains and is fine until you mash the gas again. If you ease into the throttle it will accelerate ok. Changed the fuel filter yesterday and added some fuel injection cleaner. No check engine light! So I guess my question is where would you all start air, fuel or electric?
Thanks,
