2DR LS - VERY STRANGE PROBLEM

1990 Acura Integra

Hello I have an 1990 acura integra 1.8 its a two dr and has about 180,000 miles on it. When I got this car it had a problem and didn't run, so I got it for free from my brother. I took the car to a shop and they said that I needed a new alternator and said that it would coast five hundred to do the job. I didn't have the money so I went and bought the part from napa and put it in my self which was fairly easy to do. I also bought a new battery. After that the car ran but it seemed like it was not running at the top of its game, so I put some gas cleaner stuff called heat in the gas tank but the car continued to be a little bit chugy. Then one day I was coming home from work and I was getting up to speed and when I was shifting into fourth I missed the gear and revved the car to about 4000 rpms, then I put the car in gear and kept going and right away it started losing power and the tachometer was freaking out and jumping up and down. The car ran really ruff and the gas peddle didn't really do anything when pressed. Finally I was going so slow I pulled over and the car died. After waiting about five minutes the car started and I drove home (about 15 miles) going fairly slow.

Now the car will do that same thing if it gets up to 3000rpms but I can drive it if I keep the rpms down. What could this be I really could use help here, thanks

Somethings that come to mind would be to check the EGR valve, check the timing, pull the plugs and look at them for how color/condition/etc to see how the cylinder is performing. I would replace them and check the spark plug wires closely. I would check them with an ohm meter. They must be very consistant in their readings. Back to the plugs, what you are looking for are deposits, color of the tip, etc. Make sure you know which cylinder they came out of. Let me know the findings of the plugs. If they are burning nice and clean you can regap and reuse them if you wish. They tell alot about what is going on inside the engine by their appearance.

Once you have looked at the above you need to determine if the problem is fuel related or electrical. The plugs will help a lot.
