i have a 87 iroc 350 tpi and it idles to low. it's got a brand new tps, iac, plugs, wires, computer, chip, maf, etc. the computer tells the car to idle at 550 so in park the car stalls, in gear it usually stays running but the idle fluctuates around 600 -650. engine was rebuilt before i got the car so it's possible the cam isn't stock. anyone have any idea what the problem could be?

 

do a search on ...setting minimal idle air...

 

did you check the idle screw or the adjustment on the tps?

 

yep checked the tps and the iac and properly adjusted them ... did find out however that one of my injectors seems to be bad. I'm gonna get a new set of accel 24# injectors and hopefully thats where the problem is ... i guess i'll find out next week.

 

DONT DO IT....accel injectors= JUNK.....goto; fiveOmotorsports.com, look into the 'pink' injectors

 

vacume leaks. especially around runners at the base. once you get it idling. spray carb cleaner at gaskets and see if idle changes. just one thing to check
