Question about 1999 Toyota 4Runner
Today i changed back to original plug wires and switched coil pack 1 to 3....i cleared all codes drove to the store with scan tool hooked up...ran fine to store no codes... when i came out and started it, i noticed it was stumbling again, it tru only one code this time po302.original code...i believe the wires i put in were bad or, i mixed up cylinders..i think this because i have the original code i started with before changing wires.po302...could it still be the coil pack as to it is showing a code for only one cylinder and the coil connects 2-5 cylinder? im at a lose at the moment and back at ground zero....any advice would be great...thanks

Yes. No clicking indicates a bad injector; you mentioned you had a Noid light; does it pulse?
If you remove the plenum to replace the injector, buy new plenum gaskets. You should not reuse them.
The graciousness of a FixYa rating for my assistance would be appreciated.

Ok this is sort of where I started with same problem, which at moment is not solved. You are on the right track as I also just changed my wires, although the readings from wires were ok, We also tried the coil & igniter which is simple to put in as connected by plug ins, I will warn you as I went to a Toyota parts yard $50. and they made the mistake of cutting one of the wires, to which my mechanic had to weld it together. It is held on by two bolts and plug ins so there is no need to cut! I was not getting power to cylinder 2. Thats when I can tell you that my back yard mechanic put in the injector, just to give you an indication in Vancouver, Canada it was $75. then 1hr to put in. It is a little tricky to install, and watch out for the vacuum hose for the fuel regulater as my mechanic didn't tighten it and it came loose! I have gone through a succession of things, latest being A new Coolant Temp Sensor which sends signals to fuel compression etc. It's tempermental in missing and running ruff. I am on here to try and get solutions before I take it to Toyota....arg
