I have a 94.5 or 95 Pickup. Not Tacoma. I'm having a running problem where there is a slick hestitation coming off of idle cold. Once it warms up this hestitaion is much worse. Also when the engine is warm....when the engine is rev'd it holds (maybe increases slightly) the RPM's after you let off of the throttle. Problems that have been found and havent seemed to have have in effect on solving the problem. Main powerwire to the fuse box had been previously repaired(before I got the truck with speaker wire). Replaced that wire with the correct guage wire. Also have checked/replaced TPS with no change. Any suggestions please?!?!?
