changing my fuel pump right now... problems.

a bad o2 will cause all kinds of problems. i wouldn't solder o2 wireing at all. it has a coating that has to get really hot before it will solder well. o2 extentions are cheap and should always be used.

Agreed! buy an extension and don't extend them yourself, trust us on this it will lead to all kinds of different problems. as for the broken bolt, go to Sears and get a bolt-removal drill bit and it will come right out.

they gave me some other bolts there that fit just fine. the first parts manager who actually used his head and realized that tons of other cars use MAP sensors and have the exact same bolts lol. most of them just read their computers and draw a blunt conclusion right away.

Id also get some extensions if they make them, im not sure about single wires.
After I put my headers in I went through hell trying to figure out my miss at high RPMs. I just threw parts at it and then found out I needed o2 extensions. After that I still had a miss that developed at lower cruising rpms and found out it was 2 burned plug wires.
My money is on o2s not reading right.
Good luck, I know how bad it sucks.

well you see in my other thread i put new o2's in there with real extensions. same problems still. i've also replaced the MAP sensor (it was throwing a code for that as well), coil and coil wire. it's only happening when it's warmed up, which leads me to believe it might be something dumb like the coolant temperature sensor in the WP? i've also got a TPS sitting in a box in my garage, but i doubt that's the problem... all the parts i've replaced have been parts that would exhibit these symptoms. the car's running like crap and not throwing any codes. to be honest, i think i'm just going to stop wasting my time and money on parts and just take it to a good shop to get diagnosed.

[IronOutlaw]

The air temperature would affect the car when its warm, but they are like 40 bucks and thats alot when you're diagnosing.
Have you checked every plug wire? That was the last thing I thought about on my car and two were burned. One was really close to the header and one was touching, but you couldnt see any burn marks on them.

yep... i replaced the tps... now it just sounds like it has a misfire at certain times. so next weekend i'm going to swap out plugs and wires... i'm ready for the PITA...

what plugs/wires should i go with? last time i changed them was when i put in the longtubes... which was about 40,000 miles ago... i put autolite plugs in and delco wires. what should i gap them at? what wires? I had considered OTVC setup, but i don't really like the look of wires all over my engine, although it seems like i'd have less chance of burning another wire. shit, i have a breadtie holding one of the wires away from the header, but it's still really close.. like a 1/4" away from the primary. over time, i guess this might have fried the wire...

Hell, Id just change that one and see if that fixes it.
I went with oreilly brand wires for 28 bucks and they did fine. I just replaced the two burned ones and was too lazy to replace the others.
I like msd stuff though, personally, but any of the name brands should be fine. I used the tr-55s on the firebird and they were pre-gapped. I just made sure they were the same and kept them there. I think it was .050 or .045 I cant remember.
