new problem on 96 camaro

My buddy took my headers off to drill out a header bolt that was snapped off inside causing a leak, we were unsuccessful as the angle was hard to get at, after putting the y pipe and headers back on, i went to take it for a ride, the service engine soon light is blinking on and off, with a terrible misfire, causing me to have very little power, took it to the local shop, put the computer on and read cyl 4 is misfiring real bad. Im having a hard time understanding what taken the headers on and off would have anything to do with that. What are some possibilitys that could be causing my misfire.

Also, my car was wrecked into by a penndot truck back in may, passenger side fender/hood were the main places it was hit, the frame was tweaked but not badly, i paid to have the car straightened and repaired, however, the mechanic obviously didnt complete his job as i took the car to sears for an alinement and was told my caster is 3.4 degrees off and is unable to be alined. Im trying to figure out what could be bent, spindle, control arm, shock, i purchased a shock today, and then later was told, the shock being bent couldnt be the reason my car pulls so hard to the right.

Did you pull the passenger side header? If so, you might have hit #4 plug and cracked the porcelain, knocked the plug wire loose, damaged the wire, etc.

I seem to be having issues with my powersteering, sometimes when i first start the car, its hard to turn my steering wheel, but once i rev it up a little, the powersteering slowly comes back, however while driving the power steering seems to cut in and out. Under the hood, where the powersteering fluid goes(by the battery, black box with cap) the box has a broken bolt and is just sitting there, i know it cant go far connected to the lines, but im wondering if it moves, it could be messing my steering up, if not, other possibilies.

2nd. Ever since i had the car Ive seemed to have problems with my plug wire on the passanger side burning up. I believe it is the shortie hooker headers i put on. The wire is too close to the header and heating up and burning through, i went through 4 wires on one cylinder, the only thing that throws me off, i purchased wire covers from ebay that take the heat, i put 2 covers on that wire inpaticular, and also tied the wire back as far from the header as i could, and it has burned again. Just incase Im wrong about the header theory and go through all the work of putting stock manifolds on. Is there any other possibilites?

3rd. I am very dissapointed in my cars performance. (im learning as i go, i am not very good with cars please be patient with me) I was having problems where my car just died while driving down the road, after suggestions and researching symptoms, i decided it was the cap and rotor, which i replaced, since that time, i have not yet broken down. A thing that really caught my eye was a lag in the upper rpms. my car seems to want to shift at 4 grand, feel like if i took it to 5200rpm id scatter my engine. So the cap & rotor may have been some of my problem, but it has not fixed my upper rpms. Open to possibilites for this as well

I apolgize for making this so long, Im in need of suggestions to start somewhere. Thank you
Then comes this gem

You need to provide ALL the information in one post without writing a novel to do so.

Pick one problem and stick with it until it is cleared up.

Since you first mentioned a wire problem, have you swapped any wires to see if that has anything to do with missing? Have you even bothered to remove a plug?

Unfortunately there are no easy answers that it seems you are looking for.

Last suggestion. If you have a vehicle that can't be aligned and you don't plan on replacing the suspension. By working on any other problem first. You are wasting your time. So what if it runs good, if you can't drive it for long before it wears out a set of tires and eventually more suspension components. Think man.

No, we did not take the passenger side headers off, so the reason for me not posting last weeks problem is because it has absolutely no bearing on what is happening right now. As for the suspension, i first need to find my problem under the hood, so that i can atleast drive the car to the shop to find out which suspension components may be bent. As i said, this is a whole different problem which is why i posted a new thread, hoping for suggestions. The drivers side headers were removed and disconnected from the y pipe, and were then put back on the back, upon starting, the #4 cyl is misfiring badly.

4th Gens have upper and lower control arms that locate the spindle so a bent shock shouldn't cause a caster problem. Either the upper or lower control arm, or spindle is bent. If you look at the spindle and see a single spot where there's rust it can be a good indication that the spindle is what's bent. That's not to say that the control arms or shock isn't bent also though. If you got the car repaired through insurance i wouldn't touch a thing and would have the shop that did the repairs finish them.

Just to do an update, we pulled the # 4 cylinder spark plug and wire off, both appeared to be in good condition. the service engine soon light still blinks on and off when the car is moving, when we first put the headers back on the car and i drove it down the road, i knew that something wasnt right, sounded to me to be a bad header leak, that seemed to get worse through out the trip, a road away from my house, was the first sign of the service engine soon light blinking on and off, and the car running real bad. I was really hoping it to be something with the header or y pipe, but everything was properly put back together. i really dont have the money to take it to a shop to find and fix the problem.

Your post is still confusing. You asked if taking the HEADERS (plural) off could cause your misfire on #4. Unfortunately, when I offered suggestions on how removing the HEADERS could have caused the misfire, you added more data, which makes me wonder how you could possibly thing that removing and replacing the driver's side header (singular) could cause #4 to misfire.

And I agree that you should not be posting multiple questions, totally unrelated in the same thread. The suspension question belongs in a different forum.

You really hurt your chances of getting help by 1) not including all the info up front - which basically wastes time for the people who are trying to help you; 2) writing excessively long threads that still aren't complete; 3) including multiple, unrelated questions in the same post.

Good luck.

This miss from cyl 4 ended up being the wire rubbing up against the serpentine belt. I corrected the problem with a new wire, excited to drive the car found that im still not out of the water, still have a bad header/exhaust leak, i believe its coming from the return line on the drivers side and where the headers meet the y-pipe. My buddy who was helping me with the headers just got put in jail, so im pretty much on my own. I am assuming the reason for the leak where the y pipe meets the header is there not being a gasket there. when i looked on ebay, i was unable to find a gasket for a 96 camaro header meeting y pipe. does this sound like a possibility and where could i find the gasket, is there a specific name. thank you
