hi all,
1985 190e 2.3 8v, new cap rotor plugs fuel filter air filter, made a 200 mile trip yesterday, the further i drove the less power it had, barley made it over the pass 1300 foot elevation. has 190k on it have no service history. did a head gasket on it last year, had valves and guides checked and head surface ground( minor warp of .005). have not done compression check yet. when you free rev it you get a bad bog and will not rev over 4k at wide open throttle. could this be a sign of low fuel pressure? it misfires while driving under acceleration like a lean misfire. if you drive it easy it runs ok but still lacks power. steer me in the right direction. I do not have access to a fuel pressure gauge set up, may have to pay for a pressure test. can't afford to throw money at it. any suggestions?
