stalling cold

[mcslow]

Hi newbie here, just bought my daughter 2001 corolla so she would have dependable car, so far starting out badly, busted window first nite to steal purses 175.00, fix check engine lite 3rd day 240.00 , but my concern is a stalling problem usually when car has sat for a while and you start up to go you can floor it and it will just sputter and backfire through intake then stall when throttle released, when it warms up so far no problem, and when I say floored it I only did that when it happened to me my girl complains of just stalling at idle or upon accelerating. The mechanic who fixed sensor for engine lite problem says has to have it happen when they are driving and of course it does not, I may try toyota dealer next they may have heads up if this is a common problem.

Flooring on a cold engien will just flood it. Never floor a cold engine, its not good for the engine.

I figured someone would say that, I know not to floor a cold engine, it had been running a couple of minutes, it was as I was leaving the drive

Still, a couple of minutes isnt enough for an engine to reach full operational temp.

I've copied this from an earlier post....


Here is my problem.
My truck runs like ass when its cold. I got the AAP replaced 2 times, 3 diff. people have worked on it to no avail. If I get into is, start up, and try to drive it cold, it will chug, surge, and stumble until I turn it off, go into school for 5 hours, then come out in the hot day and start it, where it runs fine. Also, if I leave to idle for about 10 mins in the morning instead of just getting in a driving off, it runs fine. What is my problem, I don't think I have any vaccum leaks, checked the fluids, fuel mix is good, and it runs fine when its hot. Even if it gets to operating temp while running it WITHOUT a 10 min warm up in the morning, it runs like crap. But, again, in the afternoon or after 10 mins of idle, it runs fine at any temp. WTF is wrong with my truck. Distributor? Carb? I'm at my wits end. HELP

with 3 people already looking at it, that should have narrowed it down a bit.....hopefully at least one of them started with a tune-up, ie. new plugs, cap, rotor, plug leads, all filters, etc. Most all people do not really maintain there vehicles that good, and when something F____ Up figure you can just change a single part to fix it. While this is possible, a good mechanic will start with a common tune-up and go from there......





...it turned out to be his distributor cap, but you get the jest of it...and remember to change the fuel filter.

Ok a month ago, my car did the same thing and I put Valvoline Fuel Injector Cleaner in it and now it works like a charm. Also the distributor could have some rust/corrosion on the contact points. Take steel wool to them. After that my car worked perfectly for having 175000kms.
Give it a shot!
