Ok i just bought an 1989 prelude but theres some wrong with the compression n cylinder 2 and something else wrong with cylinder 3 but i dont know much about engines especially fuel injected..i was wondering if any of you had an idea on what it could be?

Thanks

 

The poor compression on #2 could be caused by a number of things... bad rings, scored cylinder wall, burnt valve, bad head gasket, hole in piston, etc. This is assuming you actually had a 'compression' test done.

As for something else wrong with #3... who knows? You give no details of the "problem". Could be anything.
