Can anyone on here tell me how to reset my ltft, have had the car back 5 times to rectify a slight misfire, actually had it throw up a code of P0172 which they just cleared and did nothing else except suggest bad fuel, what a load of crap as it has always run 98 from the same servo, under load on a hill it can get to the point of running on 3 cyl, why it doesn't throw up a misfire code is beyond me, I wish to reset the trims to see if it makes any difference, it is not a coil pack or maf as these have been eliminated by checking with a multimeter when I replaced the plugs, tired of dealing with dealerships that don't give a dam with the attitude of no returning code no problem, any help appreciated. ps it also ides rough as I do not run the auto start feature.
