CAN BAD INJECTORS, CAUSE SEVERE LOSS IN POWER?

[rei-04]

well the car was running pretty good with the 19# injects, but had idling problems because the previous owner had a mass air meter (calibrated for 24# injects) So, I installed my old 24# injects on this weekend. The car does not have a surging idle anymore, but it idles a lil high (900), but it is very weak in power at WOT. It feels like a compression loss when I hit the gas pedal, but I know my compression is good because I tested it before I installed the injectors and I know the upper intake manifold is on really good too. I also put on a new 24# mass air meter by Pro-M.

If some of these injectors are bad could that be causing the problem of a severe loss in power?

Yes... it could. jrichker has a checklist for running the the injector load test. Do a forum search to find it and run the test. Should tell you which (if any) injectors are bad. Have you already pulled codes?

 

[crunchie12268]

yes

 

[HISSIN50]

yes

this has to be the most ambiguous answer to a thread ever. LOL. yes what? i thought you were REI posting to say he had done code pulling. i must need sleep.

REI, while pulling codes, do as Daggar said - it is called a cylinder balance test. it will run the injectors through a test - if it fails, it retests up to 2 more times using different criteria to determine how well the injectors are working. neat test.

thanks for the info guys. I appreciate it

I am going to go to autozone and buy a analog voltimeter now. I have a feeling it is my injectors. That means a have to deal with that pain in the a.. intake manifold gasket. well thanks again.

do you have a SD car?

i would not worry about what it might be till ya know. good luck bud.

Hissin: I think you do need some sleep ...REI said in the first post "the previous owner had a mass air meter (calibrated for 24# injects)"...

Were the injectors new?

i saw that. i could not figure out why he would need an analog VOM unless he had a SD car (no functioning CEL; analog VOM helps to pull codes with no CEL). i was just trying to figure out more info and reasoning for what was being done.

I figured you would have seen it...you read into more than I did...I guess I'm "simpler" minded than you

i doubt that - im very impressed with your posts. because im stupid, i have strange perspectives and thought processes (i had to think on this thread because i still cant figure out why Crunchie posted "yes"). LOL.
