Toyota t100 96 missed fire on cilynder 3 change wires sparkplugs and ignition coil

Yes, you may have just 3 coils you should change all the spark plugs. Use these pictures to select what yours looks like.




I hope this helps. Take Care.

Ok for code p1300 replace ignition coil 1 and 4 cilynder and for p1310 replace ignition coil 2 and 3 cilynder

move the ignition coil to another cylinder and see if the miss fire moves. If so replace that ignition coil. If the miss fire stays on that cylinder it is more likely the fuel injector. Was their carbon on the spark plugs when you removed them? This is indicative that the fuel injector is gummed up.

You said you changed the coil pack and the wires but didn't mention the plugs. Try moving one of the plugs to a different cylinder and see if the miss follows it. It could also be the ignition module. (the thing the coil packs mount to.)

everything unnecessary as the problem is the injectors /fuel pressure or injector wiring
run the fault codes first and save money

If your car is miss firing and your husband changed the coil packs,the wires leading from coil packs to sparkplugs must have got crossed.This will change car timing which will result in the car miss firing.He needs to go over wiring and correct problem for car to run right.You can go online to autozone.com and type in Info about car to get the correct wiring layout.Your problem isnt the new plugs n wires.Its the wiring layout.

main cause of firing is problem with spark plug, spark plug wire, or ignition coil of your vehicles. try a obd check up. get a detailed report on sensors. then change all spark plug. And if the problem still persists, unplug sparkplug wire one by one while engine is on. then check the difference. usually engine misfires while any plug is disconnected. thanks

They dont really go out of time...These were common for bad sparkplug wires and ignition coils having open circuts...check for spark on plugwires 1 and 4 and 2 and 3 if there is no spark on 1 and 4 replace ignition coil the same with 2,3 the coils do fire the 2 sparkplugs simultainously ..and if there is an open circut in the plug wire only one wire will not have spark..if its a coil 2 wires will have no spark..

Have they replaced the coil on #5?? There are no plug wires on this motor. They have ignition coils mounted atop the sparkplugs called COPs. If a misfire is still detected, possible coil malf or cam or crank sensor malf. Hopefully this helps
