3.2 engine, rough idle + needs a minute to run.
I have a 3.2 engine that starts fine but will not take gas and thusly drive unless it gets a minute or two warm up time. After that it runs great and starts easily after that. It has a bit of a rough idle.
The engine sat for years and was recently revived and installed in an SC chassis. The ECU was repaired, new injectors installed, new head temp. sensor, new wires etc. No vacuum leaks detected. Thanks for all the help that I have received from help this Forum has provided in the past. What are your thoughts? |

Check the fuel pressure from your fuel pump, also the fuel pump check valve. The fuel may be draining back into the tank. Also check your fuel pressure regulator and damper for fuel at the vacuum lines... Once I addressed these, my car that was stored for 13 years starts on first turn of the key, warms up at ~1100rpm for 30 sec and settles to 880 rpm rock solid.
