shawn Posted July 20, 2011 Share Posted July 20, 2011 when i up-shift ( 2,5, 4 cyl) the engine revs up between shifts. i think this is some sort of anti-stall feature and i have seen it on other vehicals that i've driven, but not quite as extreme as this.(annoying) ------- is this just a matter of replacing a sensor or....................

Geonovast Posted July 21, 2011 Share Posted July 21, 2011 Does it idle high? Are you not completely letting off the gas before you push in the clutch? Link to comment Share on other sites More sharing options...
shawn Posted July 21, 2011 Author Share Posted July 21, 2011 ya, it does idle a bit high, and sometimes it changes by itself to a higher idle yet, but nothing too drastic. and yes. i am letting off completely on the gas when i shift.. this is on my 86 btw.

Geonovast Posted July 21, 2011 Share Posted July 21, 2011 Could simply be a result of the comparatively slower throttle response of the TBI. Unfortunately I can't directly relate, as the only 2.5 I've ever owned is MPFI. The only times I've had my Jeeps rev up a bit during a shift was when the IAC was sticking, resulting in a high idle.

shawn Posted July 21, 2011 Author Share Posted July 21, 2011 i did replace the iac recently , and it did help alot and should probably look at the o2 sensor too (if i win the freakin lotto), but i am wondering about the tps ?? Link to comment Share on other sites More sharing options...
