Random bog/stall

[Fubar231]

Sometimes when randomly creeping my car will bog/stall down. It only happens when im barely on the gas then a sudden let off. It will drop to like 300 rpm and bounce around a few times, and normally catch itsself. Sometimes itll stall out though. My car is an automatic if that has anything to do with it. Any place to start would be a good idea. I don't think i have any boost leaks but ill test that here n a few days cause my new turbo should be here tomorrow. Anyways anywhere to start would be a great help.

do you have an aftermarket bov if so is it vented to the atmosphere.

No. Stock bov, mods are as follows.

Apexi intake, cooleze intake hardpipe, 2.5 inch IC hardpipes, spearco replica IC, 3inch turboback exhaust no cat, ARP Studs w/ MHG, gauges, built trans. I think thats all that really matters.

Also, it doesnt happen if i let the gear wind down in the gear itsself. Aka cruising @ 30 in 2nd then letting off its fine. It only happens when the cars sitting still normally and drive, barely touch the gas then get off.

Did you check for any Vacuum leaks? My car used to do the same thing and that was my problem.

My 89 did that as well and it progressively got worse. As told by the mechanic that looked at it it was an exhaust leak off of the turbo Y pipe if I recall correctly. For any matter it was on or near the turbo. Mine got so bad that I had to hold the gas at stops or I would stall

^^^mines was just like that. Wouldn't even idle. Had to learn how to heel and toe or die

Well if its a leak near the turbo ill figure that out friday when i put my new turbo on. Im pretty used to the heel/toe method at stoplights, i can actually just barely toe the gas enough to where the safc still reads 0.0% (Probably bad thing)
