It also dosent have any low end power its fine above 2200 rpm .


The dealer said I had to much ilde time. D&R Garage siad it was the ceps pump ?

any help would be appericated

 

From what you stated it could be a pump issue or injectors, but you also might want to check the harnesses on the valve cover gasket and make sure everthing is working right there, if you have a short there or loose connections it could cause the issue.
