Just received some bad news from Cruize Performance. They won't clean my injectors because they say mine have the highest failure rate in the industry. They are the original Multec grey/silver fuel injectors. So, anyone know where I can buy some decent replacements? The car is stock so I want to keep them at stock specs and have a limited budget. Any help would be appreciated.

 

Summitracing Go with the ford Motorsport ones.

 

You seem to have a host of problems, don't you? I wouldn't get the used ones but I'll throw in a vote for the Ford ones. They are probably going to be 19 or 24 pph ones that you get tho. Good time for you to get a truely custom EPROM for your car to take car of the richness of the 24 pph ones and optimize your engine performance.

 

Yes, I do. It all seems to point to the fuel injectors allowing too much fuel into the car and leaking when the car is off. I can really smell gas in the intake plenum when the car is off and sitting for awhile. I have also seen numerous posts that say the stock fuel injectors on these cars are crap. So I think I'm just going to replace them and if they don't help, then so be it.

 

Will injectors out of a 1992 Mustang 5.0 work? They are 19lbs and look like the same connector.

 

I guess you are needing these soon.
I have a set of 24lb Accels that I am probably going to sell once they come off of my friends car next month.
They have less than 10K miles on them so far.

 

I could wait a month, but I have read that Accels are not the best choice. Also, I don't want to get an adjustable fuel regulator or custom tune right now so I need to stick with 19lbs. Thanks anyways though.

 

you're running 19's in your 350? did you swap from a 305?

 

I would think you could get by with 24pph injectors if your stock ones were 22 pph but are you sure you have 19 pph injectors? Those are on 305s and 22 pph ones are on 350s

 

OH, I just thought I read some posts that said the 19s were stock. So that's what I was going by. So a stock 89 350 TPI L98 should be 22s? Man, good thing you guys told me that. I was about to buy some used 19s...

Here's thing. I don't want to get a custom tune and don't want to have to get an adjustable regulator at this time. So I really need to stick with stock specs. So what fuel injectors should I get then? I didn't see any Ford injectors that were 22 pounds. So am I screwed??

 

You could go with 24's ,the computer should ajust for the extra richness and bring it back to specs,plus give it a little more umph.

 

Thats what I was thinking.

$219.88

 

So I don't need to do anything else with the 24 lbs? My concern is that my car already seems to be running rich, but hopefully that's because my injectors are bad and letting too much fuel out.

So my computer should compensate? Then what about going to 30lb injectors? They are the same price. Or is there a limit on what the computer can adjust for?

Also, in my 99 Cobra, I can't just throw on bigger injectors without recalibrating the MAF. Are Chevys different than Fords in this respect in that they don't need their MAFs recalibrated?

 

You have a MAF system and the ECM can compensate to a point. 30pph is way past that point.

 

22# stock injectors, try gmpartsdirect for a good price.
