Weird Power Loss ABout a month ago I started my car at it randomly died right away. I started it back up and it hunted for idle pretty hard. After it would find idle the car want to die. I would give it some throttle to about 2k rpms and the car would randomly feel like a fuel cut off and the rpms would dip to about 500 then surge back to 2k.
I didn't think much about it cause it went away after a couple of minutes and it hasn't returned...until this morning. This time it happened with only the surging while I was driving on the road. After the car warmed up to operating temp, it went away.
Anybody have any thoughts?

Would think it is a fueling/spark issue. When wires would go bad in other cars they would surge at certain points or have a hard to keeping running until they warmed up. Could be a vaccum leek, but would have to be a big one to do that. Sounds like what my car did first time I did seafoam on it and pulled off the brake booster line. If Choco's guide didn't say it would idle funny or have a hard time running I would have thought I messed something up.

It did it again tonigh when I started it up to come home from work. I did notice that the temp gauge was not reading when the rpms were surging. When the temp gauge finally started to read it the needle jumped to 160* and the surging stopped.

We have an answer. Fix the water temp problem and see if it comes back.
Have you been working under the hood? Is the connector on tight? Any codes? Water temp is critical for the ECM to provide the right fuel.

Yeah I thought I posted up a reply last night about the coolant temp sensor. Seems like it could cause that.
