stalls only making right turns

I have an 89 RS v6 2.8L. It stall out when only making right hand turns unless i feather the peddle(tricky process but the only way). I had just recently performed a full and complete tune up from all filters to pcv valve to ingnition. i replaced the tps and iac as well as ecm but still same problem just not as bad as before. i also scanned the bugger and the code were ....."No vehical speed signal recieved", "Throttle position senser too low"( i adjusted since), "Electronic spark timing(est) problem"(i checked the timing and its proper), "EGR system problem", MAF sensor or circuit too low". I right about ready to attack the MAF sensor and hope for the best but im just absolutely stumped....... oh and i also did the timing chain and gears (they were F#cked up). if anybody has any idieas that would be very helpful.

sounds very much like an intermittant short to ground. You can get a rubtrhough somewhere on the wiring harness, that only touches metal in a certain circumstance, such as making a right turn. These are a pain in the ass to track down, i did it for about two years. its a very time consuming process. if you plan on doing it yourself, get ready to know your car very intamately. lol

yea i just found it today at work or so i hope.....so far so good. the wire harness on the passenger side of the motor was laying on the engine pipe but none of the wires were melted through. hopefully there not destroyed. but like i said so far so good.

id say thats a very good location for trouble. nice find.
