Hey y'all. I have a terrible problem with my 95 ATX that I must fix ASAP.
First of all, I had the tranny rebuilt about 2-3 weeks ago (pan was full of shavings--$1800---good?), and my mileage has gotten even worse (down to 13 mpg). I'm not even driving it that hard. I got that on a freeway jaunt from OKC to Tulsa (about 100 miles), where I only punched it twice. I used to get more like 22.
Here's the prob:
I knew it was about time to do plugs & wires, and my budget is somewhat limited due to the trans rebuild, so I mistakenly got the cheapest wires I could. Autozone....Duralast...60 bucks. Go ahead and laugh. The guy also sold me Motorcraft 32FM plugs. Didn't even give me my military discount. Grrrrrrrrr....
Anyway, I went to my friend's MG shop on the north side of town to install everything, since every time I work on my cars I always run into a situation where I need a special tool, and he's got them or a way around them. I only have a Chilton (blech...) manual, and it doesn't describe how to get at the rear bank of plugs. I changed out the front bank, and installed the new wires (he was going to close up shortly, so better to wait and tackle the rear bank on Saturday). The car ran HORRIBLY!!!! He noticed that the prescribed plugs are 32PP, not FM, and suspected the possible heat range conflict could be messing with the computer. I didn't have my code checker with me, and couldn't remember which pins to connect with the paper clip. I had to drive it home--actually straight to Autozone, since I did the idiotic thing of cutting one of the old plug wires and couldn't reinstall them. I drove about 15 miles and used about 1/8 tank of gas. That's bad, even for this car. It misses pretty regularly, and occasionally makes noises I've never heard before--weird sounds like dropping a bolt into an empty oil drum. It infrequently does some muted backfires as well. I just ran the codes, and here they are:
KOEO
335 - EGR feedback signal is/was out of range - EVR or PFE
336 - PFE sensor signal is/was was high - PFE
KOER
116 - Engine Coolant (ECT) sensor out of range - ECT
136 - Oxygen sensor not switching/system lean Left or Front HO2S - Fuel control
213 - Ignition SPOUT or SAW circuit open or shorted - Ignition Systems
336 - PFE sensor signal is/was was high - PFE
538 - System did not receive "goose" test (my fault)
I could not really warm up the car with it running this way (don't want to hurt anything MORE), so that could explain 116 and 136. The KOEO codes have been like that for some time--I don't know what to do about those.
It's the 213 - Ignition SPOUT or SAW circuit open or shorted - Ignition Systems that caught my attention. This morning I tried swapping out the possibly-bad new wires with the 3 remaining (rear bank) new wires, and there is no change. Anybody help?
