Too much injector???

[tbi92rs]

OK, here's my combo:

Rebuilt 302 w/unported E7's
Lunati 51014 cam (.500/.510 lift 218/226 duration)
cobra upper/lower intake
holley 70MM TB
Aeromotive AFPR w/gauge
FMS 24# injectors w/Pro-M 75mm MAF
Walbro 255LPH fuel pump
stock intake tubing w/K&N conical filter
shortie headers, Bassani ORX, dumped 2 chambers
smog pump and emission equipment removed (EGR valve still electronically hooked up)

Ive got gears and a clutch as well as rear control arms and DR's...and Nitrous

Her'es the problem. When you first start it up cold, it doesnt liek to dle.....let it warm up for 2 minutes or so and itll idle erratically.....kinda almost if its searching for idle, except not to a extreme extent.

I turned FP down to 30PSI and it wouldnt go any lower (vac. off). So i reconnected vacuum, double checked itming (12*) and went to put air in my tires hwile it was idling. By the time i was halfway through with the other tire, my eyes were watering and my nose was burning......so its running rich as hell. my Pro-M just got back from a re-cal, because last year it was ****ty and now it is 10x better.

Car runs pretty good. It doesnt stumble and pulls clean, especially being on stock E7's. I have no idea what it runs because i just got it going again. Ill be hitting the dyno next saturday and attempting to get my A/F correct as possible.


Question....Do i need to put the 24's/MAF away and drop my stock 19's back in? Are the 24's/MAF just too much for what my car has done to it? Im going to keep the 24's because I know Ill need em when I get my AFR's on in a few months.

Thanks for the help!

Really the 24's with correct maf should not be a major issue at idle with stock pressure setting, 30's a little low in my opinion. You can definatly keep them in place if your not having drivability issues even if they are a little big. As far as the exhaust smell at idle..I may be inclined to look at pulling the codes, and might want to check on those o2 sensors.

02's are nearly brand new...got like 100 miles on em. Ive heard 24's are WAY too much for a stock headed 302. I dunno though.

and its not throwing any codes.

I had 24's on my car with just a Cobra intake, 1.72 rockers, and some other bolt ons, and it ran fine. 24's really aren't too big for your combo. I would check some other things like codes, TPS voltage, IAC, vacuum leaks, etc. I would bring your FP back up to 39-40 with vacuum off, and you should be able to run around 14 deg of timing
