My 99 4L auto has been running great but lately after driving for awhile when I let off the gas like when turning into a driveway or something it will suddenly stall. It will start right up imediately and then run fine again. The check engine light is not on and there are no codes stored.
Any ideas??? kinda alarming when you suddenly loose power and I am not sure yet if it will happen on the hiway yet as the issues has just started and luckily I have only been driving around town when it has stalled.
Thanks
you know I thought about a fuel issue also but wonder why the truck would immidiately restart with no issues if it was starving for fuel, also it does not hessitate or run poorly before the stall.
Still I agree that it is probularly a good thing to look at changing! If I remember I think it requires special tools though.
thanks
would a malfunction with the throttle control sensor not leave a code in the computer? Where exactly is that sensor?
I was wondering if maybe the idle air control valve solenoid may be the cuprit.... tried cleaning it yesterday.
Thanks for the ideas
