I have 01 3.2 and when the engines warm it doesnt start good. It turns over 4 to 5 times before it will fire and when it does the engine hesitates before settling to the correct rpms, once running its perfect and i havent noticed any decrease in mileage. It also smokes blue for a little while. It starts fine when its cold or hot. Plugs are new and maintanence is always done on time. Any ideas?

 

Yea I have a few....
1. Take to local shop and check fuel pressure. Regulator could be out and pressure is too high causing flooding when starting hot. I have seen this before.

2. I would check the EGR valve they can get sticky and cause all kind of problems.

3. I would put OBDii scanner on it and check the O2 sensors, engine temp sensor and timing advance.

That should catch it.

Good luck

 

I already checked the fuel pressure and its to the correct specs. It also does not drop below 30 psi after 5 min(service manual specs) and the throttle body was cleaned. If thier was a problem with one of the sensors would it display on the dash when you search for trouble codes or would you need a scanner to retrieve it? Thanks for the help

 

Well you checked the fuel pressure but didnt check anything else I sugested.
Ok if it starts and runs fine when cold but not hot(you weren't very clear) YOU SAID when the engines warm it doesnt start good. It turns over 4 to 5 times before it will fire and when it does the engine hesitates before settling to the correct rpms, once running its perfect and i havent noticed any decrease in mileage. It also smokes blue for a little while. It starts fine when its cold or hot. Apparently according to you the only time theres a problem is when its warm, not hot or cold.
Then check IAT sensor, and ECT sensor.

 

Yeah it only starts rough when its warm, if its cold or hot it starts good. I didnt get to checking the egr valve yet and ill check the sensors. Thanks
