i just replaced my heads on a 02 and now its very hard to start and has a very rough idle. i have checked and rechecked eveything, im at a loss.

 

did you put distributor in wrong?
try moving it with it running to see if it helps. are you getting an engine light. alot of people tend to forget to plug the cam and crank sensor back in, lemme know how it goes ive done a lot of these, im an auto tech

 

well on an 02 there is no timing adjustment. i have pulled the distributor twice, set the motor at tdc and still the same problem. im having to hit the gas to get it to start and hold down the accelerator to keep it running. ive checked all the connections on all the sensors, all are plugged in good. the only thing im unsure about are the ground wires on the back of the drivers side head. i had on pull out of the end and spliced the two together. didnt know if this may cause a problem or not. what are those ground wires?? also could the injectors have come loose by turning the intake upside down? i never took the upper off.
