my car boggles when i keep my gas pedal steady?!?! why does it boggle like that? it accelerates normally but when i ease off to drive at a steady pace, it boggles but when i step on the gas, the boggling stops. does anybody have a clue of what might be wrong? afm? btw, i have an 86 corolla gts.

Too much gas.
The black smoke is a giveaway...

But pulling from my experience with tuning the carb jet on the scooter...too much gas, the things starts bogging down.

Tune down the gas a bit and your problem should go away.

Too much gas meaning too much fuel in the fuel/air mixture.... :grin:

your afm may be, hmm. gone, or miscaliberated.

Try your oxygen sensor first...

could also be that you have a super dirty air filter.

or fuel filter

you might just be able to adjust the throttle cable

driiift_hachiroku · 05-14-2002, 04:01 AM

your ECU has gone into "closed-loop" mode, which is basically, there's a problem so the ECU tells the fuel system to go into limp mode and therefore dumps as much fuel as it can into your cylinders to make sure you never run lean and blow the motor.

Sounds like either an electrical problem like the wires going to your oxygen sensor to your ECU has fried, or your oxygen sensor is actually fried, or ECU, or it can be any number of sensors.

Tell FatRedCircle (Peter) to give you an ECU, an AFM and borrow a Oxygen sensor....change one thing at a time and from there, you'll be able to diagnose.

If the problem still exists, it might be any number of things, but try those first.

lemme find out how many o2 sensors i got on hand. and i got a spare ecu, and afm i think laying around

as for the probelm
it might be your cold start injector.
as it would pump more fuel into the engine =D
just osmething to think about

fatredcircle · 05-14-2002, 01:13 PM

lol

pwrupae86 · 05-20-2002, 01:07 AM

yah, i'm from socal...but i will pay for shipping if you can let me have the ecu and o2 sensor but that's not gonna happen. :sad:
