Rich at idle and low speed, almost loading up. Detonation top end. I pulled some timing out of it but no difference. There is no steady ck engine light. I only get the ck engine light on cold mornings and it is intermittant. Under throttle it comes on, when I let off it goes off. HMM I am thinking o2. Any ideas, without going to the shop and spending $$$.
Thanks

Ya I would check those 02's, are your cats still on the car? I would check those out to.......do you know what your fuel pressure is at? I would put some higher octane gas in their until you figure it out if you haven't already. It may help some of that detonation your having.

ok, cats are comming off, next week. Running 93 octane and I pulled some timing out of it. Still lean. So, I will take care of the cats, then o2, then adjustable feul pressure regulator.
