Having problems with your 1998 Dodge Grand Caravan ?
Had the check Engine Light Code TPS Po123 High voltage. Have replaced TPS twice. Check voltage is reading fine. Checked pins and added electrical grease. At times when resetting code or taking of and putting back on or replacing the TPS all will run smooth for a while then it will start to sputter and jolt while accelerating from stops and othr times as well . What do I do now?
Have you cleaned out and tested the throttle and body itself? Tested any relays if there are any on this one?
