Hi I’m Tom and I’m here to assist you with your issue today. Before I get you a fully researched answer, I have to ask you a couple preliminary questions.Is the check engine light on and was the DI cassette ever replaced ?
Customer: replied 4 years ago.
no check engine light and this has no di cassette
Have the fuel injectors and mass air flow sensor been checked?
Customer: replied 4 years ago.
Sorry thought I mentioned...changed fuel injectors, checked coils,compression...no mass air flow check...I have a 04 can we use this one as a check? or do you know a better way to check
Yes try the 04 and see if it makes a difference let me know.

We didn't swap the mass air, we unplugged it and no change
Ok if when you unplugged the mass air flow sensor and there was no change there should have been and thats telling you the mass air flow sensor is shorted out and needs to be tested correctly and most likely replaced for this issue .I would focus here next for this issue.Remember Im here if you need any further assistance for anything at all it will be for no further charge.Please rate excellent service so I can get credit for my help thanks.Bonuses greatly appreciated.

That did it....thanks...the cooling fans also come on when car is parked,so when you come back out it has a dead battery...it isn't running when you park it though...any thoughts on that?
Great glad to fix it it the other issue is either a faulty coolant sensor or fan timer.Remember Im here if you need any further assistance for anything at all it will be for no further charge.Please rate excellent service so I can get credit for my help thanks.Bonuses greatly appreciated.
