Yea so i've had slight throttle hang for quite a while, it was pretty bad during the summer so i changed the IAC, and that helped a lot... up until recently i'd idle around 800 and the hang was very brief.... My VSS has been out of commission for a few months now so i brought the car in and my mechanic said we should try a ford IAC to make the throttle hang disapear, and he replaced the VSS.... Now the spedo works (which is awesome) but the car idles at 1500 and if u tap the gas it climbs up to 3000rpm for about 10 seconds then drops back to 1500 (shifting the thing is not fun with this condition) just wondering if anyone has any thoughts....
Also at idle u can hear an intermitent misfire if you listen really close..... So far this is what I've done to the car...
Changed plugs to autolite double platinum (this is when I started having the slight misfire problem (which seems like it might be getting worse)....
Changed the coil pack.... didn't help....
Cleaned out the TB.... didn't help....
CAR RAN FINE THIS MORNING EXCEPT FOR THE SLIGHT MISFIRE PROBLEM (WHICH IS MOST NOTICABLE IF U SLAM THE GAS AT LOW RPMS, IT KINDA SPUTTERS A BIT)...
Then my mechanic butchered the car today and now i got the worst case of throttle hang ever, all he did suposedly was try the new ford IAC, which according to him made it even worse, and then put mine back on (which I replaced last summer)....
I've reset the computer, started the car multiple times, tried running some fuel injector cleaner through it.....
I'm an idiot so if anybody's got any ideas or suggesstions i'd much appreciate it....
