I have a 89 civic hatchback with a 90 integra Ls motor its loses all its power at 5200 but it use to hit around 6500. would that have to do with my screwed up timing or what?????!!

 

Or your O2 sensor or your spark plugs or you need to change the oil or you need to replace the rings or ..........

Do you burn oil?
Have you done a compression test?

 

dont burn oil, runnin really rich, timin belt real loose, havnt tested it yet for compression or leak down or any of those good test yet. bout to change oil in the next couple of days. spark plugs are brand new and gapped. and throwin a code 43 on the ecu. it deals with the fuel suply system. i have the new timin belt and all the things i need to fix it but cant get the crank bolt off.
