Hi,My name is Tim,
I will do my best to assist you
did you do the complete tune up?plugs,rotor,distributer cap and the plug wires?
tell me all you can
Good morning Tim. Yes, i did the complete tune up. plugs, rotor, cap wires and a new DIZZY. The check engine is blinking, P0301 ,P0302, P0303 P0304 and P1399 comes up on the scanner. I reset the ECM and the Check Engine comes up on the next start sequence with P0301 and P0302 set right away and the other two sometime in the next couple of start/stop sequences.
The car belongs to my Daughter-In-Law and I just learned the codes were set and the car Idling rough for at least 4 months. I'm sure you know how that goes!!LOL!
I read that when the Check Engine light is blinking as a direct relationship with the misfire codes, the CATs may be in trouble. But as I said..there is PLENTY of power. It jumps right up to 7000 with no hesitation. The Idle is quite rough and the exhaust has the tell-tale sound of a miss.

I have replaced the distributor,(DIZZY). I assumed the ignition pack, which tends to degrade and cause these symptoms. No Joy.
Yes. The complete distributor. Brand new.
Ignition coil is in the distributor. Entire distributor was changed, new.
A friend has a graphing OBDII hand held. The o2 sensors are performing as expected. Fronts are large swings and rears are stable. I don't think anything as violent as the timing belt skipping teeth has occurred, I will try the injector disconnect and check the timing. I did unlock the distributor and swing it full throw, the idle changed as expected but did not effect the rough idle.
