First, you didn't mention a cap and rotor? Second, you should have the tps voltage up at .54 or even a little higher.

I set mine at .60-.65 It gives a little better throttle response and doesn't throw any codes. As far as having a miss, replace the cap and rotor and check over all your wiring on the ignition box. I'm curious as to how the engine ran before you started throwing parts at it?

didnt run when i got it po said he put new distributer on and forgot to boult it down jumped time so i set distributer then it would start and stall after one or two seconds found out it was a bad injector on bouth sides of rail witch shut down the injector pulse now it runs grate no smoke changed plugs no sign of oil burning just when ya wana stomp it it skips like spark is arking maby shitty 7mm plug wires cant handle extra volts think there super max 13 7mm wires there new thought was changing all intake gaskets plus injectors might as well due plugs wires all sensors hole tune up fuel pump its my day to day car so dont need break down o got new adjustable fp reg to for hell of it

If you are not running any aftermarket chip in the ECM, you could bump the timing up to 8 and try it. Are you disconnecting the EST wire on the firewall when you adjust the timing?

jman1234

yes i un plug it and it runs more slugish at 8 better at 6 dont know y but seams run bogy at 8 deg

Then i would keep it at 6. I guess you won't know till ya get home and check the cap and rotor and go from there.
