2000 T & C Random Surging / Almost Stalls
Update:
2000 Chrysler T and C 110,000 miles 3.8L, Auto LXi model The random no start condition has not reoccurred for quite some time. Now the situation has changed somewhat; the vehicle randomly starts surging and almost stalls. Here are the conditions: Idle;(750 to 1000 RPM), engine warm or moderately warm - When placed in gear rpm's swing by up to 400 rpm both ways. Engine almost stalls, then races. Timing swings from 7 degrees to 23 degrees. Getting onto the on ramp the other day, after a moderate amount of time for engine cool down (approx 30 minutes from normal operation temp) the engine had intake backfire two or three times, then ran fine. 90 Percent of the time, it runs fine. Other times, does this randomly. Using an Actron scanner and looking at rpms and spark advance PID's is where my info comes from. Need a better scanner, the frame rates are too slow.... Shows no codes in the Actron Scanner, set or pending.... My thoughtsare:fuel pump, crank/camsensor, ECM. Since the problem is intermittent, this would seem to rule out the plugs, wires,fuel filter, and vacuum leaks. Might be the EGR though, but it seems odd this would occur randomly at idle conditions. Idle air controller would throw a code..... Fuel pump might be intermittent, but I have no TSB's that show failure occurring at this mileage. Will check with an installed gauge, but it's hard to get the vehicle for that long.... Any thoughts? Fred |

Well, Alldata swears that this tsb doesn't apply. We've tried several times to get them to send it, but they only said "no" and then said they will extend the subscription for 30 days for free, since they can't find it....

Hi Moe
When posting TSB, most people use alldata. You and I use Techconnect. So the information we send may not be the same on alldata. I am not a big fan of alldata. But you are right, Don't use the vin number. |

Thanks guys! Getting it back today and will be able to really look into it. Thanks again!

We replaced the CKP first (swore it would be the one!), and this did not fix the problem. We then replaced the CMP, and this solved the problem. The vehicle started up and exhibited the same problems initially, but only for a short time. It got better quickly; the plugs may have been fouled by the overly rich mixture. The vehicle now has 45 miles drive time on it, and the problem has not reappeared. We intend to Seafoam it, and replace one questionable vaccuum line. We will continue to post info here as we get more on this vehicle. |
