The car is completely stock. Based on what'* written below, it'* good that I have been babying the car for the past couple months. Though I've gone WOT handfuls of times and now I'm nervous.
My first run was before I changed the plugs. I saw 3.5* KR giving it half throttle at most, less than 50 mph. I stopped right there – changed plugs and wires yesterday – NGK TR55s.
60*F outside, coolant at 180*, trans at 185*, I'm seeing 6* KR or less. I saw 6* when I was closest to WOT on the highway above 70mph. Even with cruise control on at 68mph, I saw 1* KR pop up and trickle away, then 1* KR popped up again and disappeared. That seemed like false or "phantom" KR to me
Besides the 6* KR run, every other time
I see KR it is at least 2–4* and I'm just cruising around town at less than half throttle @ less than 50mph. Every time I give it any decent amount of gas I'm seeing KR.
Things I should do:
–Regap my plugs to .055 (they are at .060). It would be great if this was the sole cause of the KR but I highly doubt it.
–Check fuel pressure
–Various other small tune-up things - how much could a bad O2 sensor affect KR? - my PCV looks fine)
I also should check other parameters on the Aeroforce too, specifically WHEN I am on the throttle and getting KR, but after seeing what I have today I don't want to get on the throttle at all. I'm seeing way too much in stock form. I guess I'll hold off on an intake for now.
Any other suggestions? I haven't found any vacuum leaks. All hoses look good, EGR looks good on visual inspection.
I think I have the major things to do down, I'll see what I can find and update this thread as I go. Keep in mind, I have not done ANY tune-up things to the car since I got it besides the plugs and wires yesterday. The old plugs looked fine too. Even still, I'm surprised I'm seeing the KR that I am seeing. I guess it'* time for some routine maintenance and hope for the best.
PS. My trans also gets up to 187* while cruising at 65mph for 30 minutes on the highway. Isn't there a tranny cooler on this damn car?
My 94 never got above 150 on highway trips.
