I'm hoping someone can give me some guidance on my current problem:
98 TJ 4.0 154,000 miles. Just replaced the battery, fuel pump, and AC relay. Today, while sitting at a red light, transmission in neutral, clutch out, suddenly the engine reved to max RPM's by itself, just for a couple of seconds, then went back to idle.
So now, on the way home the engine would completely cut out, just for about a half of a second. It appeared as if everything electrical shut off like I turned off the key. The cruise control reset to off, the gas gauge went to E, all as if the key shut off. Searching this forum it seems like it might be the throttle position sensor (TPS) especially with the over-rev problem happening first, but I'm hoping someone can give me some confirmation on this. No codes, just cutting out.
