Who did the work? What size injectors?

Improper tuned FRP and dumping *** loads of fuel. Miss timed motor. Wrong fuel pump.

 

all the work was done myself and the injectors all i kno is oem

 

frp? what does that stand for?

 

typo. FPR fuel pressure regulator. If you have the OEM one it could be bad. Have you checked the injectors resistance and see they are good?

sorry read ur post wrong fpr in new so i kno its right

 

Fuel injectors not plugged in correctly from the harness?
