chrysler 2.7 engine pulsates at high rpm

Jul 12, 2014 10 Replies

when I rev the engine it gets to a certain point and starts to pulsate. If I try to go higher it appears to have a govener and won't let the engine go any faster. Can anyone explane this?


How many miles on the car? Has the fuel filter ever been replaced?

check engine light?

has it been scanned for codes?

The car has 133,000 miles. I have never changed the fule filter or the fuel pump.

Yes. P0340 and P1391 come up when the car stalls.

Hope this helps...

Thank you for your help. You gave me some interesting things to check. The starter and battery. I hope they work too.

I don't know how different the 2.7L engine is, but the camshaft position sensor was very easy to replace on our '02 300M (3.5L). Maybe $10 or less for the part from AutoZone.

Since you've got two codes that want to point to the cam position sensor (and related wiring), and only one of them also points to the battery or starter, I wouldn't expect it to be that.

don't assume its the sensor. it could be the cam sensor harness too,

and lets not forget the timing chain.

I appreciate the suggestions. Looking at them I think my next mission is the cam shaft sensor and it's wiring. before I start going into the motor. I will post what happens. thanks.
