Car Trying To Stall.

[KezR33]

Hey guys,

A while back I asked about my roaming idle which I thought was nearly making my car stall. I haven't driven my car much lately so its taken me a while to diagnose the problem (plus its gotten 10x worse) but it seems its no the idle thats making the car nearly stall its the throttle.

Everytime I push the throttle my revs drop to the point the car nearly stalls before picking back up. Even if I'm sitting in neutral or with the clutch in, just genetly tapping the throttle will cause the revs to drop suddenly before picking up again. As you can tell the car is mongrel to drive atm and I'm terrified of doing serious damage to the engine so I've parked it till I can get to the mechanic.

The TPS was replaced recently, so I'm thinking they're related. Hopefully the mech will work it out, but it doesn't hurt to come armed with a bit of research.

Cheers.

Use a multimeter and set the tps to factory specs

if its about to stall while idling. unplug your afm. see if it idles perfect, then if it it idles perfect. plug it back in. if it starts stalling then most likely afm is the problem.

i have the same problem, except when i unplug the afm and try to start my car is doesnt start at all!! but when i plug my afm back in it starts. the idling problem is still there. So AFM is the problem???
