well after toiling with my truck for the last few weeks it is finally running right! for those that don't know i ran new underdog plug wires and all of a sudden around 1800 rpm under load the truck would shudder and misfire. it was running multiple miss fire codes. so after checking the plugs coil and wires for problems and countless hours of head scratching i gave up and went too ford apparently i did everything right but my injectors were bad?! so i has those and my front pinion seal replaced , and the truck runs like a dream.

my question is would new wires foil the injectors or have they just been on there way out and new wires were just the last nail in the coffin, or was it complete coincidence?

and thanks to John and Rick for their help answering earlier questions.

 

Sorry we couldn't nail it for you -- glad someone found it. That can be real annoying, lol.

Doubtful the wires did it. Could just be "one of those things". Maybe an injector body was damaged at the connector and you bumped it putting the wires in and that broke it the rest of the way or something -- who knows?

I'm sure it's nice to have it back running properly!

 

All good im just glad its taken care of the truck had to go in for a new pinion seal anyway and i was done messing around with the ignition. now we know another posible thing for the next time this question gets asked.

 

It happens all the time at my work, I fix something and something completely unrelated will fail. Its hard on the shop because we get blamed for a failed window motor when I did a intake manifold. It "was working when I brought it in" kind of deal.

 

ya thats gota suck, for a shop. its weird how some times doing one thing right will cause a hole slew of other problems.

 

Bad injectors? As in plural? It's not often that more than one injector at a time fails. And even a single injector failing is not that common.

I'd like to hear more from the Tech who did the work...

 

ya me too, Im at school now so i havent got a chance to talk with the guy so im going off what the invoice said. from what i can tell they were all either "rebuilt" or replaced. my money is on they finaly craped out after i hydrolocked my truck 2 years ago.
