if the lc-1 is reading dead lean, than means fuel is on teh sensor. What does your VE table look like in the idle cells?

Try unhooking the TPS.

Full lean is consistant with not firing one coil, or really bad timing. :-)

Did you calibrate your TPS? I always forget to do that on mine, and things get better (but not WAY better) when I do...

Ok hustler, thats why it was reading dead lean.

you know what, I dident calbrate my TPS... would that be it? I only have a manuel TPS tho, on off switch.

My VE table and rq fuel are the ones that Brain sent me for his car with 460cc injectors, it should be ballpark..

The manual TPS is useless, you can't hook it up. If you want a TPS then convert yours with the Wells part or grab the Bosch unit.

My idle was misfiring and smelt really rich, but it was actually lean as. Once I richened it up heaps the misfiring went away as did the unburnt fuel smell. Maybe this is the same as your case?

sabo, it cant, the plugs get so much carbon on them, it is running pig rich.

Here are some pictures of the bord.. anything wrong? Q14 and Q15 are removed, and R38 and 37 are jumped.

I would still do as the guys before said start by verifying spark on all cyls.

They do run on only one coil. Belive me.

Good luck.

Ok, im getting spark.

Maybe im not decriptive enough. When the car is on MS, I start it and ir runs while im giveing it some gas. When its running, its VERY sluggish (barely revs), smalls of gas, is running way rich, and doesent really idle.

wtf?

I put my 305cc injectors back in, so I calculated the rq fuel using 13.1 a/f. My whole VE table is the one you gave me.

I am about to give up... idk what it could be.

Are you sure you use the right outputs for the right coil/ignitor? They still start when swapped.... I know this for a fact.

Good luck

Did you check your timing?

Also, 13.1 fuel is pretty ridiculous. Calculating the fuel should be done for 14.7.

if your using my fuel map, use 14.7 for AFR. so req_fuel = 8.9
