3800 Getting frustrated...

[zeez gtp]

Well I just payed 90 bucks to get my injectors cleaned today and it helped a little. I was gonna meet with Justin on Saturday to have him do it, but he was busy. I figured I would go here cause I am sure Justin is gonna be real busy with the twins. The mechanic was telling me that my car smells like it is running lean. He recommends that I get bigger fuel injectors. He said my car is to modded for stock injectors. Are my injectors just shot? I mean, I have 105k miles on the car. Do I need to get bigger injectors? I don't really see any people with bigger flowing injectors unless they are really heavily modded. Would getting my car scanned figure out the solution. I mean, I got the fuel pump replaced, new spark plugs, and got the injectors cleaned, and it is running better. It still boggs alot. Thanks

You do not need bigger injectors. But if I am not sure if they are bad or not

FUEL PUMP ? FUEL FILTER ?

The first step in diagnosing fuel delivery problems in fuel injected vehicles is to VERIFY that you have proper fuel pressure at both idle and under load. You need to get a fuel pressure gau8ge that you can monitor while driving hte car.

Base pressure should be ~52PSI. Under load for each PSI of boost increase, you should see an increase in Fuel Pressure to correspond. So if you have a base pressure of 52 psi and you have 10 lbs of boost, you should hit 62 PSI of fuel. If you do not, something is wrong.

See what your injector pulse with voltage is aswell.....You should be good...Who told you you need bigger squirters?

Who told you you need bigger squirters?

The guys at the mechanic shop, but then they said that my exhaust caused all this, but I have had the exhaust for over a year, and tons of people run the same style and setup. Who knows. haha

what he ^ said

So what is the complaint? Lean condition? You said something about a bog. How many miles do you have on those 104's? The colder plugs have to be changed more often. The race plugs go bad faster under dailey driving conditions.

I just put new autlo lite 104 platinums in on saturday. the car got alot better when they cleaned the fuel injectors. if i got wot instantly the car bogs, but if i lean into it and then go wot, it is alot better and almost feels perfect.

 

[JonPGTP1]

Hmm...coil packs? wires? I was having a bogging prob too.. i switched 2 coil packs and it went away.

Symptoms of a vac leak is what it sounds like to me. What are your LT's like? If you want to scan your car, shoot me a pm. I'm out by Weber/Boughton in Bolingbrook.

If you wanna try new L67 injectors, i have some for ya to borrow.

100k miles, worked perfect when taken off and cleaned 20k miles ago, shoot me an IM

 

[zeez gtp]

well the car is fixed now. it was just the spark plugs wires. i never really thought it would be them since they are taylor's and only have about 20k miles on them. i put stock ones back on thanks to james, and the car ran awesome. i just picked up some factory ones and put them on. james let me know when you want those wires back. thanks for letting me borrow them

Hey Fredo.....Did you get that?

Sorry guys, Fredo (MyblueGTP) was having the same symptoms. I wanted to conver that to him.

Odd those Taylors went bad so fast. Did you burn one or something? If not send PRJ an e-mail. Let him know your not happy. Maybee he will take care of you.

ya i figured they would of lasted alot longer. i don't know what to look for if i burned one? if you mean on the outside, like if it was resting up against my headers, no. i had them all clear from that stuff. i know when i took them off, the piece you connect to the coil, those metal peg things were really dirty, so i cleaned them up really well. who knows. all i know is that the car is running really well now and i am happy.
