Van running like its missing


the problem is not in the plugs , wires , cap , rotor but in dirty injectors or injector controls and wires
use a quality injector cleaner for a few tanks of fuel
ECM controlled cars do not a tune up as the computer does that 60 times a minute so all you need to do is to run the fault codes and fix the faulty sensors
fault codes are being recorded all the time and only the serious engine or transmission faults put the engine light on

1991 Honda Accord Miss-fires dies


I would try replacing the ignition control module and the distributor pickup as the next most likely cause of this problem. Also I would do the following

This problem can be caused by a dirty automatic idle speed control valve and throttle valve. Buy a can of throttle valve cleaner from NAPA or Carquest (made by CRC chemicals) and spray it into the air intake while the engine is running, use up about 1/2 the can, engine will try to stall hold the speed up, shut it down and let it soak for 30 minutes, restart and blow out the remaining fluid, shut it down and disconnect the negative battery cable for 5 Min's to reset the base idle control

the only reason it stoped missfiring when idleing was cause your moter was running off the extra boost of the carb cleaner try replacing the plugs and wires before doing that again boss. and you can fid out if its a hard miss by power braking put it in drive and keep your foot on the brake then increase the gas till the car tire just starts to slip if it misses really bad u have a hard miss caused by a coil pack or really worn spark plug or bad plug wire.

Engine missing at high speed


Start with a tuneup. Change the air filter, plugs, cap, rotor. See what happens. Check ignition wires, if damaged, replace. I assume it idles correctly and runs fine at road speed. Dirt fuel injectors will also cause this as they try to send more fuel through dirty injectors.

I had a similar problem in a 1994 Taurus, and after spending nearly 300$ on ignition parts, it turns out the problem was a bad spark plug wire that cost me 8.88$ to replace.
