2.7 missing, runs smooth over 3,000 rpm

I have a 1995 tacoma extra cab 4X4 2.7 auto trans. We drove to a town about 15 miles from home to get a new freezer, run fine going there and around town, then we pulled into parking space at Sears and before I could put it into park it died. Tried to re start but no luck, wife smelled gas so I held it to floor and tried again it hit a time or two but no start. We went into Sears and let it sit a couple of hours but still no start. Anyway we had someone pickup us up and left it sit at Sears over night. Next day we loaded some tools in our van and went back to Sears. I pulled a couple of plugs and they were very wet had some wear on them and the gap was way to wide, .060. I went and got new plugs, coil and distributor cap and rotor button, this model has coil in distributor, put the new plugs in and it fired right up but would miss just above a idle and smooth out at 3,000 rpm. Anyway, we got our freezer and headed home, going up a hill on way home it quit again,put the new coil, cap and rotor on and got it started and made it home and started checking it out, the + wire on coil had some insulation gone like it had been hot and two terminals on the igniter looked like they had been a little warm. I repaired the wire and checked pickup coil , condenser and MAF while blowing air through it with an ohms meter and all checked good, TPS checked out ok. pulled EGR valve, it was closed seems to be ok. haven't checked IAC yet, don't know if it would cause this as truck idles ok, maybe to much fuel pressure? Has anyone had this kinda of trouble? If so what was the cure?

 

Nissan 2.4s had a photoeletric sensor inside the distributor that would go bad and cause weird stuff like that. Not sure if the toyota has an equivalent or not. But it sounds like a sensor that has gone marginal so the computer can't advance the timing properly. ie crankshaft, camshaft or a distributor sensor(of some type)

 

Fordless, You may be right, there is a pickup coil, acts as a cam position sensor in the distributor and a igniter on the on the fender well that tells the coil when to fire, can't get the pickup coil without buying the whole distributor and the igniter isn't cheap either. what ever it is it happened instantly at a idle while parking, so I would think something electric? didn't know if the pickup coil or igniter worked or didn't work.

 

You my friend are in need of a junk yard.

 

I put replaced igniter with one from junk yard and seemed to help but still missed, couldn't find a used distributor in my area, so I bought new after market one on e-bay ,now runs like new. Old one checked good and I had put new coil, rotor and cap on old one, but I guess the pickup coil was bad even thou it tested good with ohms meeter.
