check engine light came on again today
P0301 misfire detected cylinder 1
P0302 " " cyl. 2
P0303 " " cyl. 3
P0304 " " cyl. 4
P1300 dont know
P1399 manufacture controlled igntion system or misfire (pending code)
The spark plugs are gapped to specifications
The distributor and cap are in excellent shape
The timing is within specifications which is at 13 degrees
Still can't figure it out??? Any ideas?

valve and vaccuum problems can cause misfires too.

map sensor and tps are not reversed? all connectors are firmly clamped on the terminals of the ICM using needle nose pliers? you still never answered if you checked your coil? im assuming when you say you checked your timing, there are also no noticable pauses in flashes. you checked injectors? hows the idle? hows the fuel pressure? dont forget to check what GScivic7 mentioned.

Here is a start:
The scan tool indicates Diagnostic Trouble Code (DTC) P0301: Cylinder 1 misfire detected.
Misfire detection is accomplished by monitoring the crankshaft speed with the crankshaft speed fluctuation (CKF) sensor which is attached to the crankshaft.
If misfiring strong enough to damage the catalyst is detected, the MIL will blink during the time of its occurrence, and DTC P0301, P0302, P0303 or P0304 will be stored. Then, after the misfire has ceased, the MIL will come on.
If misfiring that increases emissions is detected during two consecutive driving cycles, the MIL will come on, and DTC P0301, P0302, P0303 or P0304 will be stored.
NOTE: If some of the DTCs listed below are stored at the same time as a misfire DTC, troubleshoot those DTCs first, then recheck for the misfire DTC.
