24# in stock a 94?
Hey guys, long time reader, first time poster, so be easy on me.
I bought this car with these injectors in it(running like crap, but the price was right), and besides some exhaust stuff, I dont see any other mods. Now I'm getting around to fixing it and I'm stumped. Its a T-5 trans and when I push the clutch in, it will rev up a few hundred rpm, wait there a few seconds, then slowly come down. Its worst on the 2-3 and 3-4 shift, but always does it. Here's what I've done so far: codes set both banks rich installed 2 air fuel ratio gauges to monitor O2's. They seem to be switching normally. I found that at WOT it runs near the rich limits of the O2's. Turned the fuel pressure down to 32, no change, so back to 39 checked timing, its at 13 degrees tps voltage at idle was getting stuck above 1 volt when snapping the throttle, so I replaced it. no change in behaviour but the voltage is good now. cleaned the IAC while I had it off, it looked fairly new and non-ford Failed the echeck, but not for HC! High NOx! EGR valve holds vacuum, I took it off and blew air through it and it seems to be ok. I swapped a new one to check but no change. Maf was cleaned with some CRC electric parts cleaner and the air filter was checked too. WTF? should I swap 19# inj back in? I thought the ECU could compensate for the 24's, especially with the FP lowered. I'm getting short on ideas real fast. Sorry if this was long, I wanted to be accurate. Joshua |

Do you have a MAF sensor that's calibrated for 24# injectors? If not, put 19# injectors back in.

If I have to, I'll reinstall some 19# inj. Does anyone have a newish set they'd like to trade for my 24's? Or a recalibrated maf? |

Does anyone have a recomendation on maf sensors? I'd guess my housing is big enough for my motor but what have you all experienced?

I was fooloing around and I found this:
