Started throwing codes (mis firing cyl 1, 3, and 4) Replaced teh plugs with NGK BRK7E gapped at .30. Started the car up and it was fine. Took it out for a ride did a couple of pulls, Parked the car and let it idle down and the codes came back. Checked the plugs and they were really white. So i tested the coil and it checked oout ok, The cap, rotor and wires are all new. Should i move on to the fuel system next. I'm running Rc310 injectors with a bull ---- blue box. Let me know what you think.

white = lean most times.

what exactly is your setup? how much boost?

what does that blue box do with timing? anything? maybe kick it back a couple degrees, you hearing any detonation at all?

Smooth_Imports

blue box oonly controls MAP, and fuel. I'll play with the timing .

david_jones001

maybe those injectors are the problem

FooK

time for real management? you ever had this thing on a wideband to see what its doing? or you just a "throw the kit on and rip the throttle" sort of guy?

You're not getting enough fuel. Sell that ---- to somebody on H-T.

Get some 450's and Uber.

I don't know how the blue box works, but if it changes the signal from the map then that directly affects your timing.

yeah i know i just don't have the cash right now. No i've never had it on a wide band. I'm just trying to get it running good enough before i take the 40 mile trip to the shop to get it tuned. I don't feel safe taking it any further then aroudn the block the way it's running.
