thanx for reading...

while driving my car just started acting up... whenever i would press down the gas pedal the rpms started decreasing and the car stalled i was able to go for a little longer by pumping the gas but after awhile it just died again.... i pushed it to the side and start it again but it idle rough and when i pressed the gas it made it worst and stalled....

if i let it idle with out pressing gas pedal, the rpms will slowly decrease and go off again...

btw its a 91 ka....

ill try to post vid when i tow it home...

vids

you can here the weird grind noise (tranny i think)

thats what i thought too, but i bought a maf and did same thing.. i tried one that i had laying around and nothing...

at least i got it tow to my apt... goodbye 40 bucks

Its weird cuz with maf unplug it will idle but gas pedal kills it
maf plug kills it slowly.

gonna check vaccum lines too...

oh and now it make a loud squeeky noise when it starts... it seems its coming from tranny...

It doesnt really sound like it'd be a vacuum line to me.

myzislow · 05-23-2007, 08:16 PM

crappy videos are up... thanx

SiI40sx · 05-23-2007, 09:30 PM

I THINK it might be that your injectors took a crap, how many miles does your car have? It has stock injectors correct?? Do this, try unplugging one spark plug wire at a time and start it to see if it'll turn on the same way, if it does its because every cylinder is working expect the one thats unplugged. If your car doesn't even start if you unplug X spark plug wire, its probably because that cylinder was one of the only cylinders working and trying to keep the car on. GOOD LUCK!!!

This happened to me before, my fuel pump took a shit. Replaced it after that everything was fine. Check your fuel pump.

mRclARK1 · 05-24-2007, 01:05 AM

Fuel pump or injectors. The whiny noise you're hearing may be your fuel pump taking a shit and not your tranny.

Good luck.

91rps13 · 05-24-2007, 04:20 PM

thanx everyone will try your suggestions today.... i always wanted to upgrade to a 155 lph pump

91rps13 · 05-24-2007, 04:21 PM

it has like 120k miles and am pretty sure injectors are stock ones(fuel pump too)

na3j nitsuj · 05-24-2007, 10:01 PM

I have the same problem on my car. My car bogs but after waiting for few mins it will not bog down until i turn off my engine and start it again...

goodluck!

skylindrftr · 05-24-2007, 10:10 PM

might be the tps if ka's have one, i noticed when I set mine wrong on my sr if I pressed the gas the rpms went down if it was a certain voltage. try setting it to what hte fsm says the voltage should be.
