I POSTED A FEW DAYS AGO OF A POSSIBLE IGNITION SWITCH PROBLEM WITH MY H22A (jdm) IN MY 93, BUT DID NOT RESOLVE MY ISSUE.

I'D LIKE ANYONE AND EVERYONE TO GIVE ME THEIR THOUGHTS AND INSIGHTS ON WHAT COULD POSSIBLY BE MY PROBLEM. HERES WHATS HAPPENING:

AFTER THE SWAP THE CAR RAN GRRRRRRREAT! FOR ABOUT A MONTH, VTEC WORKS, GREAT MPG, NO ISSUES AT ALL. THEN SLOWLY I STARTED FEELING A JERK FORWARD/LOSS OF ENGINE POWER/SPARK/OR FUEL DURING ACCELERATION, BUT AT RANDOM POINTS. ITS BEEN GETTING WORSE AND WORSE UNTIL FINALLY IT WILL JUST NOT WANT TO GO AT ALL.
HAPPENS IN ALL GEARS AT ANY SPEED BUT USUALLY AFTER OR AROUND 3K RPM. FIRST I THOUGHT IT WAS FUEL FILTER OR PUMP AND REPLACED BOTH BUT STILL IT CONTINUED. DIZZY IS BRAND NEW AND NEW IGNITION COIL (external). ALSO THE FUEL INJ. WERE CHECKED OUT AND THE PRESURE IS GOOD.

ANY, AND I MEAN >ANY< IDEAS ARE WELCOME HERE. THANKS EVERYONE

It's cause your caps lock button is broken.

What Have You Already Done To Try To Fix It?

To Indylude18: Ive replaced fuel pump and filter thinking it was a fuel delivery problem but neither one of those fixed it. I checked all my grounds also. im going to replace spark plugs next (even tho the ones in are brand new) but they are the 3 prong, more expensive, not sure what the brand name is- ones. so im going to get some NGKs single prong and see if maybe its just missing spark. also i read to maybe check the current going to the ignition coil..

Have a CEL?
