I recently replaced a cylinder head on a 96 intrepid and a week later the valve spring broke causing alot of other problems. I replaced the head AGAIN and it was fine for about 3 days. Now its suddenly running bad and has a code for MAP sensor (no change from start to run). Map sensor is not the problem and I have vacuum and power at it. I would greatly appreciate any help.

With a multimeter set to the 20 volts scale backprobe map sensor connector terminals ground and signal return. Turn key on and observe reading. Watch meter as you start the engine. The voltage should have a dramatic change. If no change, leave meter connected and turn key on engine off. Pump map sensor with a vacuum pump. As you apply vacuum map readings should drop off. If the reading doesn't change, replace sensor. If the sensor reads ok check wiring to sensor from PCM. If all checks out ok perform a compression test on all 6 cylinders and install a vacuum guage. Any compression problems will affect vacuum. Map sensor will pick these vacuum problems up and if they are bad enough, set a code. Good luck and let us know how it's going.

Thanks! I will try it next week. I was way too busy to even open the hood on it today. I run a 16 bay repair shop by myself and it gets a little crazy sometimes. Its great to know someone like you is out there to help. Thanks again!!!

Well, I found the problem with the Intrepid. Oddly enough the problem was a broken exhaust valve spring! Apparently Chrysler is having alot of problems with them on their remanufactured heads. Thanks again for replying to my problem and again I'm glad there's people like you out here to help me when I get in a jam.
