1990 Hyundai Excel Engine problems

Engine sputtered, stopped running, caught fire. *Ak

While proceeding up a slight incline during the commuting hour, the car lost all power and I came close to being hit in the rear. After about 30 seconds I regained some power and was able to proceed. The car was idling rough and I had to keep my foot on the accelerator at all times to keep it running. I had it turned up and it ran better but still a lack of power. I had to have it inspected and it failed inspection because the pollution was at 1200. I then had it tuned up again (fully) and it failed again. I had it checked out at a station and found out that cylinder 3 did not have any pressure at all. I also found out that to get it fixed it would cost around $1,000. It still is not fixed.

Engine locked up while driving at 20-25mph. No prior indication or warning. Dealer contacted and no warranty. Vehicle was towed, repairs can be remedied at owner expense. *Ak
