So heres the deal. I just installed a crower 2, valves, valve springs, retainers, ported/polished head, and edelbrock IM. I got the idle straight, it idles at around 1500 once warmed up....but after driving around, when i come to a complete stop, the idle drops to about 500, and wants to cut off, so i gotta keep my foot on the gas....and its a real pain in the ass. ive tried messing with the idle screw, but it still wants to drop low after driving around. anybody got ideas of what it is and/or how to fix this? thanks in advance!

what kind of tuning are you using? If none, there's your problem. When I was using this cam, I had almost 30% of fuel take'n out in idle range just to get it not to stall

Can i temporarily use the SAFC/VTEC controller from Fields alongside a stock P08 ecu for this?

It might give you a marginal improvement however without adjusting the timing to compensate for the addition or subtraction of fuel, you won't get the optimal results.

you need to tune plain and simple... you wont see any gains without it and your car wont be running how it SHOULD

installing a cam and tuning go hand in hand

Worry about emissions when you have to. For now though, you have to do it for your set-up to run right. If you won't tune it properly then you shouldn't have even done it.

If you're worried about emissions here's what I would do. Tune the current cam using OBD1 w/ Uberdata, Crome, etc and then when testing comes around, swap back to the stock cam and obd2 and you should be golden.

OK. Well i checked my CEL codes, and it came up Fuel Trim Malfunction, Fuel System running rich, and O2 sensor malfunction. Clear codes, turn car on, idles and wont run right again. it ran fine with the CEL on :-(

edit: and switching to a stock cam everytime emmissions comes around wont cut it either. will a functioning AFC tune the car on OBD2?

Tighten the trottle cable or turn the idle screw all the way out to make it idle until you do it right and get it tuned. My guess is the car will stay idling around 1000 rpm
