Grand Caravan Hard starting, rough idle

Sounds like a fuel ctrl or temp sensor problem. Fuel pump must be conducted with a volume and pressure test under load. Also electrical integrity of the pump. Fuel injector must at least pass a residual test. Whatever service make no difference if the cpts has a problem to begin with. We cured 50% of injectors by servicing it but the other 50% crapped out too. So. That don't mean nuthing. Also injectors can be tested by flowing or a 5 gas on & off test. Thats a sure thing. It could be also ur coolant and intake air temp sensor operating out of range. The computer detect a false temp but it can't tell from 43 deg or 90 deg. Good luck man. If I hear 1 more of these stories everytime I get I penny.I'll own 1/2 of texas.

Good luck man
