Turning right/fuel issue
(92 Mustang GT Convertible 5.0)
(MSD Ignition System)
Car runs fine. Whenever I stop and make a right turn however, the car loses fuel and lose the wheel straightens back up and i play with the gas a little fuel kicks back in and everything is fine again. Sometimes when taking rights, say into gas stations etc where I can't give it a nice amount of gas to catch and go the car shuts off. But, I am able to stop throw it in park and start it right back up.
Any suggestions or possibly someone who has dealt with this same issue would be much appreciated. I would hate to have to take it to a mechanic and pay out the *** for a simple fix.

Being a 92 i am going to assume it is still injected, if its carbed now then it turns this into a different sort of problem.
Im willing to bet that if you tried it would do it during a left turn also. Im guessing that you are going to full stop for your turn sence your talking about parking lots. Your air bypass valve is dirty and sticking. When the wheel is at full lock the powersteering pump puts a higher load on the engine. At idle or just barely off idle the computer tries to compensate for this by inceasing idle speed but cant because the bypass valve is sticking. Pull the bypass valve off and clean it out with carb cleaner. If it repeats this in the future replace the valve.
ETA: while you are cleaning, pull the throttle body off and clean it, it is gunked up also.

I hooked it back on and took it for a test ride around my neighborhood now it does it during left turns, right turns, and while sitting at an idle. So it lead me to believe that yes indeed this is the problem. How do I reset it so the computer can relearn the airflow?

your computer isn't going to relearn ****. If you car still has the problem, your issue is elsewhere.
