after I drive it around for awhile, i parked my car.
an hour later car won't start... engine turns but does not start.

After few more try, engine finally starts but stays in low rpm and makes prr prr prr prr sounds for about 10 sec and back to normal condition again...

This happened during morning start as well...

car starts but stayed in low rpm making pr prrr prr sounds then goes back to normal...

nebody else experienced this problem?

 

Check sparkys and ISC valve.

 

will do.. i think it may be my ecu wires...

 

/\ why? souds like the fuel temp sensor. it is supposed to up the press during hot starts via the fpr solenoid. i though it did it for like 10 sec or some set # after start up. it is fine first thing in the morning?

 

it starts but rpm stays low and engine doesn't revs up way it suppose to..
Why do i think it my ecu wires? some wires are f'ed up.. thats why
