injectors

A quick two questions for anybody out there . . . . . . are those ACCEL 24 lb Injectors as good as Mid America make them out to be. I was thinking about getting a set. Also would a MSD Ignition improve performance?

Can't comment on above injectors but the ones we like are from RC Engineering http://www.rceng.com/

thanks for the info ZR1 Mom. I called RC Engineering, they recomended serviceing the injectors that came with the engine first. . . . . . I might give it a try. Thanks again.

Not a bad idea, they can clean and flow test them and worse case maybe have to replace one or two if bad but it would save you a lot of money.

I hard them don on my C4 clean and flow tested.

Run's great.;bt

That's good stuff Butler but did you mean the Accel's or did RC Engineering service and flow test the old ones?

Some good info from one of my members:

"I recommend removing the fuel injectors and have them flow tested.

I just did mine and I had 5 bad injectors 2 primary's 3 secondaries one was dribbling fuel the others were pulsing but no fuel was coming out!!!

Only indication I had was on the dyno I put out 319 rwhp."

After getting the info from you and Butler. I decided to take them out this Sunday and have them serviced during the week. This way I can get them back before the long weekend.

Tell me ZR1Mom, do you have to get new injectors when that happens or are they good to go after they are serviced.

I guess it depends, if the internals of the injector is bad then you would have to replace the injector.

One of the issues with these injectors from GM is that they use a steel ball inside the injector which can rust, stick, etc. Cleaning the injectors in many cases will fix this but if bad enough you will have to replace the injector.

What is nice about after market injectors like from RC is they use Stainless Steel balls so they don't rust.

So even if your stock injectors work today or after being serviced doesn't mean they won't go bad again down the road. One thing that can help prevent this is to throw in a bottle of fuel injector cleaner. I recommend Red Line as it is a detergent based cleaner and won't hurt the injectors.

Good to go. That will be my weekend project. Thanks again for some good gouge . . . .

Relative to your fuel injectors in the future it would be advantageous to use 3mm fuel injector cleaner every 6mo. You can get it from some local auto parts like carquest.You also need a kit to use the cleaner because you attach it to the fuel rail and disconnect the fuel pump @ the gas tank and start the car and let the car run until it stops. Just follow directions with the cleaner.This is the best fuel injector cleaner I have found.

Thanks for the great tip. A lot of the new cars today are being produced with a carbon fiber plastic for gas tanks. Especially, the PT Cruisers and C5's. Some of the additives that you put in the tank to help clean the fuel injectors and fuel systems are actually disturbing the tanks and ruining the pump or fouling the injectors by breaking down the tank material. The way you suggested, is great because it bypasses the tank. A little more work but more efficient. Again, thanks for the tip.;bt

Good point Larry, you need to make sure you use a detergent based fuel injector cleaner like Red Line.
