Car:
1990 245 with stock motor and automagic transmission
Symptoms:
When making left turns, as I straighten back out and get on the gas, the car will cut out on me for a second or two, then return to normal. It feels like it's pulling spark or fuel. The car won't stall, it holds idle fine, and runs like a champ in RH turns under load and in neutral. While it's cutting out, it will eventually fight through it (usually 2-3k rpm) and then take off again.
So I figured it was G-loading a wire and shorting it out. However it seems entirely related to steering wheel positions rather than severity of the turn.
-So I tried a fast LH sweeper with little steering input but high G-loads, nothing.
-I tried a hard 90 RH to shake it loose, and nothing.
-Then I tried a painfully slow 90 LH with some steering and no G-loads, and it cut out.
-So then, at a red light straightaway, I turned the wheel to the left, then straight, then hit the gas... and sure enough, it cut out!
I took a quick look under the hood, and nothing is pinched around the steering lines, or down around the rack itself. I also checked connections at the coil, reset the ECU by disconnecting the battery, and ran it without the MAF plugged in, and it made no difference in the problem.
I'm going to to put the car in time-out to think about what it's done, and this weekend start cleaning electrical connections/change the fuel filter/etc.
Does anyone have any idea what could be messed up?
Possible Causes:
I brought the car as a loaner vechicle at the last rallycross:
The bumps or dirt could have been the cluprit, but it ran fine for a few days after the event. Could also be that the cat has broken loose and is turning sideways???
Also at the rallycross, the intake pipe came loose, and sucked god-knows-what into the engine, so when I got back home I cleaned out the MAF with specialized MAF cleaner, and cleaned the throttle body with carb cleaner. So the cleaners could have damaged something, or sent something downstream to foul the O2 sensor?
Thanks,
