Hesitation for first 2-5 minutes in the morning

posted by  someone claiming to be HenryC on  Tue Jun 28 16:24 CST 2005 [RELATED]

I had a similar problem with a 92 turbo. I believe it was caused by a poor connection at the EFI temp sensor. That sensor is under the intake just past midway toward the firewall. I removed the connector (a tight fit), took the spring clip off and squirted some contact cleaner on the connector. I cleaned it by plugging it in and removing it about twenty times. It seems to have taken care of the problem. If this helps, I would suggest that you clean all your EFI connectors the same way.

I usually put a drop of tuneup grease on the connectors to keep the corrosion down. The FAQ has a pretty good write-up. Do not use the tuneup grease on the O2 sensor, the voltage is too low and the grease will interfere with the signal.

My symptoms were poor running for the first minute and then everything was fine.

I would also suggest checking for diagnostic codes.

Good luck!
