i have a inline 4 cyc eng that as of late will get warm and peg at 2000/2500 rpms, why is this? i changed the fast idle motor cleaned the [COLOR=green! important][COLOR=green! important]intake[/color][/color] and bought a new egr valve. i feel it could be the tps but i have been told it could also be a heat sen.

this being a problem has caused my front trans seal to leak BAD and i have to get this fixed as well but i need to narrow my problems down with this idle problem before i do the trans or i will mess the other seal up as well. this car also has the c-5 od trans in it.
should i have the trans rebuilt as well or replacing the seal should work?

it could be your oxygen sensor my car does the same thing sometimes haven't figured it out yet but it also hasn't happened for awhile either
also your choke might be sticking so check those 2 things and u should just be able to replace ur seal and not have a problem but inspect the area of course hopefully this helps

it could be that your ford oxygen sensor might be bad and needs a replacement. anyways, have checked for some leaks? have you done some tune-ups lately?
