I am trying to find where the ECM is located. It appears I have a preoblem with mine.

2000 Dodge Intrepid. Took to shop to have the water housing replaced and the thermostat replaced because the car got real hot. When I picked up the car and drove it to work the cruise control did not work, the rpms at times in the parked position would be on 2000 and it would jump irratically while driving. Once I reach 70mph everything seemed fine. When slowing down or increasing speed it would happen all over again. Returned it to the shop thinking it was a vacuum line problem. They now tell me the computer in bad because they could not get the diagnostic equipment to read or find any codes (nothing showed on the computer). The day it was being repaired they did a diagnostic and told me the catalytic converter was below threshhold. What could have possibly been done to ruin the computer during the repairs? I thought they may have not taken the negative lead off the battery and shorted the computer or created and surge that sent to much power to the computer. How do I verify? :Lol:

Do you
have the same problem?

PCM is on the left side of the engine compartment in front of the strut tower, but I dont think that is the problem. If Im not mistaken, the upper intake has to be removed to gain access to the upper housing they replaced. This problem could be a vacuum leak under the upper intake. The PCM's are very durable now days, it would be hard to hurt it by unhooking and reapplying power

Was this
