Im having serious A/F mixture problems....help?

[The ANTI-RICE]

Well, few days ago, i adjusted my JR FRP, and my B&M FPR up about 5psi, and it was running 2 yellow 2 green on the A/F gauge.

However, its BACK to dropping to FULL LEAN at around 6,000 rpms. What is my problem? Is it just the 10degree cold weather that is wreaking havoc on my A/F settings?

I pulled all 4 of my spark plugs(BKR7E-11)and noticed that they seemed grey-ish, tan-ish. However, the 2 in the middle seemed a TAD different than the ones on the outside. They were the tannish color, but on one side they were more WHITE.

In the post that ZIP related to me about the JR FRP, he said "DIAPHRAM INSIDE THE JR UNIT WAS VERY INCONSISTENT"? Could THAT be my problem?

All this has happend before, last year actually. I did nothing to fix it, then one day it jus started running RIGHT again. The car still pulls as i remember it to, and breaks the R LSD loose in the top of first still.

WHat the hell is goin on with my car? Would/should i be worried?!

Thank you,
Tony

I think it might just be the weather. The temps are around 10 degrees here and I know that I have had to raise the pressure up to 95 psi with the 310's to keep it where it normally is with warmer temps. My normal top side pressure is 80-85

My first JR FPR went bad AFTER I tried to adjust it. It was never the same afterwards. It performed erraticaly.

Holden, thats exactly what im thinking! Maybe i should go ahead with the VORTECH/CARTECH unit?

I adjusted the JR FPR a tad more....we'll see if this works!

Yeah. Get a Cartech.

Even if you don't need the adjustability it offers, you won't have to worry about what the hell it's doing like you have to do with the JR FPR.

You could try to "recondition" your JR FPR by screwing the adjustment bolt all the way in, then back out to where you want it. It might help.
