i know this has been over-discussed already because i was just looking at a lot of threads the other night. anyway, my problem. i've been having weird idle/ acceleration problems lately and i want to chek my tps to rule it out or fix it. jeep is a '94 by the way, everything i find is about pre '90s so maybe mine can't even be adjusted, d/k. i tried to check the voltage like i've read but can't even seem to get to the terminals without disconnecting the plug. any easy way? and what voltages should i like for? all this assuming i can even check it like the pre 90s. sorry if it's confusing, just need some help.
