I recently took the tii out for a 20 mile trip and the car starts, runs (seemingly) fine, and even hit a mixture of freeway/street driving. The issue that I noticed this time is that randomly, I'll get a complete loss of throttle. Engine completely unresponsive to throttle engagement.
I had this issue so I coasted off the freeway onto the service lane and the engine suddenly kicks back and I got throttle response again. I resumed driving to my destination with no additional hiccups.
On my return trip hours later, I took a right turn to get onto the freeway and the same issue occurred again. Complete loss of throttle unresponsive to pedal engagement. I thought it was a fuel pump issue but the engine never died. It hovered at 1k just nonresponsive to throttle. A few moments later, I got throttle again and was able to get back onto the onramp and continue my trip back home; again without any further hiccups.
I'm a little at a loss for what this might be. I thought it was the fuel pump however the engine never died and I've already had the fuel pump replaced with the Bosch e28 fuel pump. I've also changed out the fuel filter up near the radiator. I've already had a new set of plugs, wires, and distributor cap installed with less than 4000 miles on the set however granted that was back in 2016 when I got the car back on the road.
I've been reading this might be a coil issue? Could this be a ignition issue? Should I replace coil, points, condenser, cap? When I did the plugs and wires back in '16 I used NKG BP6ES and it's ran fine to this date.
Let me know what everyone thinks.
