Tony302600 Posted July 12, 2007 Share Posted July 12, 2007 Ok guys, I have a 95 F-150 5.0L. Int. stalls per customer and pings, mainly when he goes to park the car low speed manuevers, with A/C on full blast, in reverse, and cranking the wheel over. Tried IAC no fix, he wanted a cap, rotor, plugs done so i did. Set timing down to 8 degrees for ping concern ( never verified it ). TP voltage is a .9v, and max at 4.5v. Did idle relearn strategy ( disconnect IAC, and bump up idle set screw, then plug in IAC and disconnect battery for 30min. Nothing. Fuel pressure is ok, egr valve vacuum hose disconnected, still happens. Ive never been able to get this truck to stall while driving going to a stop. Only time ive gotten to stall is when ure turning the wheel with A/C on full blast, in reverse. It doesnt have a p/s pressure switch. I've tried everything any ideas. No codes by the way. im leaning torwards TP sensor, but i dont want to throw parts at it. Quote Link to comment Share on other sites More sharing options...
DwayneGorniak Posted July 12, 2007 Share Posted July 12, 2007 Is it an EEC Five MAF system or is it still the speed density system? I've seen dirty MAF sensors cause that. Quote Link to comment Share on other sites More sharing options...

DwayneGorniak Posted July 12, 2007 Share Posted July 12, 2007 Check your MAF for being dirty. And I always look in the PCED manuals at reference values to find out what the MAF sensor should read with KOEO. Quote Link to comment Share on other sites More sharing options...
kevin phillips Posted August 26, 2007 Share Posted August 26, 2007 check your baro reading on scan tool compared to another vehicle in the shop.if its off i'd look into the maf being dirty also Quote Link to comment Share on other sites More sharing options...
