91 Doing Funny Suff?
Hi I have a 91 F250 351 I have put lots of money into this truck in the last year, finally have it running pretty good, now a nother problem.when I come off the highway say doing 65mph and come to a stop at a lite or somthing,It shifts up and down up and down until I come to a stop.It also is not starting very good in the morning takes 2 or 3 times to start and smells rich. It has new plugs rotor cap egr plenum gasket checked cat new muffler computer indicates rich cond. this motor was just changed ,the original motor had air pumped into the ex manifolds for idle emissions,the new one does not ,could the way I hooked up the emissions (AIR PUMP) be effecting the truck,there is no check engine lite coming on . Any Ideas would be a help THANKS
