My 2000 caravan runs fine until it reaches operating temperature, at that point it starts to intermittently stall. I'm unable to determine whether it is losing ignition or fuel. Which is the most likely suspect?
What is your question?
The exhaust sound is similar to that when there is water in the fuel. Codes logged are P0340 and P0740. The stall starts gradually with no power, then power resumes and increases in frequency until it is just no power and shut down. As soon as it cools, it starts and runs normally.
What makes this problem better or worse?
It is only present when the engine is at operating temp.
How long has your 2000 Dodge Caravan had this problem?
RepairPal Certified shops can diagnose and repair your 2000 Dodge Caravan. They provide transparent pricing with a minimum 12-month or 12,000-mile warranty on repairs and services.
A good scanner would help a great deal here. PO340 can indicate a faulty cam sensor. It's possible when that sensor heats up its failing. If you have a scanner that can read live data from the engine sensors you can determine if that sensor is not reading when hot.
