OK heres the deal.... my timing belt came off sending my piston into some open valves. Alright so i pull the head and take care of the bent valves with some spare valve train i have around. replace the timing belt and head gasket. I ran a compression check multiple times and came up with roughly 200psi across the board. Ok so bent valve situation solved. I try to run the car and it idles HELLA choppy. Im throwing codes 71-74 which is random misfire of 1-4 cylinders. i cant figure out why its acting up....it ran PERFECT before the timing belt came off.....i checked timing over and over again....all my marks are dead on and timing is good. If anyone has any suggestions/opinions id love to hear em. thanks.

Wrong forum man, codes 71-74 do not exist in obd-0 land... I think.

Anyway, try a leakdown test.

 

Check the dizzy, a friends GSR did that after a bad miss-shift. He ended up selling it like that so I don't know the likely solution. Check the plugs/wires/ignition components. - Darrell
