RICH idle

[kroberts]

Holy shit, this thing is killing me. It's idling so rich that my eyes burn. I have a fresh '97 OBDI S52 with ebay headers, 21# Accel injectors, 3.5 inch HFM, 413 DME with an older TMS chip, I've installed the O2 sensor in the pre-cat port in my ebay header. I had to disconnect the vacuum hose for the brake booster to get it to idle without surging. I dont have a tach yet so I cant tell you what it idling at. When I plug the brake vacuum port, the idle turns to shit and it starts to surge.

I know 21# injectors aren't excessive but what about them not being OEM parts? Anyone ever run Accels?

I'm going to try that CRC brand MAF sensor cleaner I guess.

Fixed!!!

I had put the HFM in backwards. I cant believe I did that. It runs like a top now.

I'm happier than a catholic priest at a cub scout meeting!!!

The throttle response is awesome, the open headers dont hurt either!
