No Mods. Stright 2000 GT. Regular fuel.
Just changed plugs, used Denso Iridiums a month ago at 99K miles.
I first cleaned the throttle body, and the idling problem got better (less frequent hesitation) No other problems.
To eliminate the bad idling, I cleaned throttle body again (with the GUNK brand throttle body cleaner, didnt let any of that seep into the manifold, put a cloth) and MAF sensor using this site as the guide. This fixed the car idling/ dying problem.
Two new things occur immedeatly after I cleaned this.
-NO hesitation, at low RPM (below 700). but now I can feel shakes
really bad misfire[/color] , the car wants to pull at Idle and shakes a lot[/color] .
-While accelerating the car trips/jerks at 3000 RPM and forces the RPM drops to 2800[/color] . Like sensor or somethign is refusing to let it go above.
I checked engine codes[/color] , I got multipile Misfire (P0300, I think) and MAF malfunction.
