240K miles; Have replaced: Plugs, wires, valve cover gasket (oil was getting on plugs), thermostat (overheating - still does once in a while), injectors and engine cleaned.
Cold start: rpms 1100-2000, if I drive it at this, it misses and hesitates - after a mile, it straightens up. Or I wait until the rpms get below 1K and it runs ok. If its short trip to the store, getting gas, etc, go to start it back up…
Warm start: rpms 100-300, white smoke cloud out the back end (smells like anti-freeze), missing, all kinds’a rukus! AfLess than a mile, it straightens up. Tonight, it wouldn’t start at all once, twice, then hit on the 3rd time.
It drives fine.
There is a leak of some sorts in the front of the engine below then valve cover (leak not from there). I am using about a gallon of water a week. I’ve spent over $400 on the things mentioned above and can’t afford anymore guessing. Help?
Codes before all the work done above:
P1457 – Leak Detected In EVAP Control System (could this be causing all the trouble?)
P1399 – Wait To Start Lamp Circuit
P0304 – Cylinder 4 Misfire Detected
