Engine Performance problem
2001 Dodge Intrepid 6 cyl Front Wheel Drive Automatic 159000 miles
Sometimes on cold start up, sometimes on deceleration, sometimes on neutral acceleration I get this chug-chug. Not sure if it's an electrical mis-fire or rich fuel dump causing it. It always clears up by itself if I let it idle for 15 seconds or so. 2.7 fresh rebuild (rings, valve job, gaskets, bearings.) Do I have a dripping fuel injector? Is it a weak secondary coil circuit (coil on plug)? Bad (inaccurate) TPS input? EGR sticky pintle? Any help would be useful please.
Oh, and no hard P-codes (no MIL light on)
have the same problem?
