You sent me alist of thing that might be wrong with my car and my garage fix everything and it still does it I will explain what it does. Start car drive for 5 miles you go to punch it and feels like its flooding out

Best start by checking fuel pressure if its within specs -

I had technician check that and everything checked out. Anything that has to do with fuel has been changed and is brand new. It is a new engine had local motor company put it in I have a lot of money tied up in the car and it still dont. I had several technicians look at it together they have over 100 years experience in this feild and not one could fix it

Before I can continue I need the fuel pressure-both at idle and 2K rpm
March, 12, 2010 AT 2:34 PM
45 idle 48 2k

Did they check the knock sensor could be retarding ignition timing

Would a code show up if thats the case
March, 12, 2010 AT 3:39 PM
Its suppose to work that way but at times they'll be a problem within the engine management system that the computer failed to lock-in and pop the CEL. Scan the computer again might give you something

Well there was no codes that showed up I will try the knock sensor can I ask you where that is located thanks for everything I just want to get my car running and tired of paying mechcanic and still dont have a running car I hope I can find the problem because im going to take it back and show them I fixed it ha ha ha
