Congrats on the repair. I hope it lasts a long time for you. Nothing better then being satisfied with your vehicle.

Nothing your mechanic has told you sounds anywhere close to being correct.

I'm sure he's got plenty of experience, and maybe there was a miscommunication on what the actual repair was.

A well maintained 5.4 will struggle to get 17 mpg on the highway unless you're doing about 65 mph. The wiring harness has absolutely nothing to do with how long your injectors stay open. Injectors aren't adjustable, and if they were, and you could set them to 4lbs, your truck wouldn't run.

For all you know, this guy could have cleaned your throttle body, kept for truck for a week and charged you $900. I would get under the hood and look around for evidence of the repair. New clean injectors, or dirt rubbed off the connectors of the harness where he was working.

You sound young, or maybe not that knowledgeable about cars, and that's fine, but people like that are easy pray for mechanics.

X2^ No one is taking a shot at you, either your mech was just messing with ya or he has no clue about things.

Yeah this is all total BS... as others said, no way you'll see that much increase in MPG, 17 I would say would be the MAX and that would be if you drove across the state on the highway doing the speed limit every day.

Also all injectors do is open and close, they have nothing to do with PSI. That's all controlled my the fuel pump, and a PSI of 4lbs 1) wouldn't mist properly and 2) wouldn't give you enough fuel.

I'm thinking he may have changed your injectors and done a small tune-up, not including plugs, and then the truck sat there running up the labor bill.

I'm curious what injector he used... all of the decent ones I've seen are 40-50 a piece. We're not trying to bust your ***** here, just don't want you to take the long end of the shaft

Sounds like the mechanic made out great on this one.

Yeah, sorry if that came off kinda ********ish. But mechanics prey on people that don't know anything about cars. That's why forums like this are around. If there's anything you're unsure about, ask away.

Sounds like the repair worked and if he did change the the phasers and injectors for $900 that's not bad. If he would have not added the BS about the 4lb injectors and the 25 mpg bs you wouldn't be getting any grief over your post.

No phasers just injectors. I did get the the receipt for the old injectors. 125.00 at his cost. This guy works at a shop and does side work at home. He is a master certified mechanic said he charges 65.00 a hour and it would take 12 hours to change and make sure they are setup correctly. I'm not seeing the mileage claims from 17 to 25. Even I said that won't happen. But he never said that at he start it was just to fix the code for low fuel. Whatever people in here want to say us fine I'm not a kid I'm 52 so I don't put up with BS.
Bottom line my truck hasn't had a issue since I got it back.

This was some of the stuff he was trying to explain to me. I'm NO mechanic so I'm sure some was lost in translation you guys feel free to flame on.
