I had an issue the other day and am curious what others may think the issue is...
Driving the H3 on the highway about 70MPH and the outside temp was about 100degrees here. Went to pass, stepped on the gas and the engine revs shot to/past redline in an abnormal way, engine performance died and then picked back up and continued on. Engine temp was a little left of the red (hot) indicator. My thermostat is one that runs normal between half and 3/4. I come to a stop in traffic and when I hit the gas pedal to accelerate, I get near zero response from the engine. It is bogged down, pedal to the floor and there is minimal acceleration to the point I have to put on my hazards so that people know i'm not moving very well. I managed to limp the truck home like this for another 40 miles. If I were to get the truck up to about 50 MPH, it seemed fine, like there was no issue. You could really only notice when it was time to accelerate.
Well, I got home that day and haven't driven the truck since (about 2 weeks now). Today, I go out to test drive it and it drives fine as if there is no issue at all. I got the truck warmed up but didn't run long time on the highway. I cleaned the air filter and intake about 6 months ago. About 130k miles on the truck. Same exhaust manifold/CAT from factory, same throttle body, spark plugs probably changed around 100k miles.
I have a few ideas as to the issue, but am looking for others to provide any similar experiences.
