had to do a head gasket and got that finished. Put on timing belt with both cam gears aligned and crank aligned after doing the two revolutions and they lined up perfectly. car idled like crap..... Got it scanned and it still says code P1390 camshaft/ crank timing misaligned... what could it be?????????

did the cylinder head get decked?? if so how much was taken off?? what is the new head gasket thickness??
did the cams get taken out at all??
are the cam gears on correctly?? there is a 2.0L side and a 2.4L side on the opposite side of the factory cam gears.
