tommorow my car 350tpi camaro is getting new 19lb ford fuel injectors, new o2 sensor.the old fuel injectors some of them were stuck open when i bought the car so i don't know how bad it affects there performance, and i am also gettin the cat gutted.do you think i will notice a difference?

 

If you had bad injectors, then new ones should give you easier starting and better gas mileage, maybe a little more power. If the injector wiring is defective, that could cause the injectors to ground and dump fuel. This will still happen if the problem was not the injectors themselves. Probably nothing you'll be able to feel, except the mental sotp difference that comes with every mod.

 

why 19 lb injectors?

 

reiterating what zippy asked. 350s came with 21# injectors stock.

 

Uh, 22, actually.

19's can work with a mild 350 better than 22's. Up the fuel pressure to compensate for the lower flow area, the pressure drop will vaporize the gas even better.

 

Well, that and the ford fuel injectors are rated at a lower fuel pressure so they are actually more equal to what would be 21 in our cars.

 

oops, my mistake

 

88, Finally getting this injector thing done. Excellent. Let us know how they turn out, I'm curious. Those injectors you got are almost 1/2 price of new ones.
Thanks,
Jeff

 

Yes, the lower price of the f*rd injectors is why many people go with them.

Again another error with 21# injector as stock for a 350, try 22#.

 

Ok, z28, that was already said, and if you are talking about my post I didnt mention the stock size. I said that a 19# ford injector would equal approximately a 21 in a gm vehicle because the fords are rated at a lower fuel pressure so when you run the higer fuel pressure that gm used it runs about 21 like I said.

hey guys,


sorry i didn't get back to you guys sooner i have been busy working.Anyways they are in my car has a lot better throttle response now.And it does not smell like a skidoo. The problem i have now is the car after its warmed up will idle really low then back up to normal idle then down low then back up and it keeps doin it.Do you guys have any idea what it could be?
