Our restoration technician Jon has been carrying out his final checks and repairs on the 1998 Morgan 4/4 before it heads off to its new life with its lucky new owner.
”Carry out appraisal. Refit brake pedal rubber. Tighten steering column pinch bolts. Raise and inspect. Check gearbox and rear axle levels. Grease up. Remove wheels and inspect brakes. Clean rear drums and shoes, refit and adjust. Refit wheels and knock up tight. Inflate tyres.”
”Get off ramp and run up,outside. Warm up and carry out road test to fuel station. Return to workshop. Flat performance and won’t rev out past 4,000 rpm. Try diagnostic computer but will not communicate with power train control module.”
”Check HT leads. Remove spark plugs, clean and regap. Refit and grease HY leads to seal. Run up and test but still won’t rev out. Clean out throttle body and refit intake pipe.”
”Look into running fault. Disconnect and test Tps. Remove and test Iat sensor. Bothseem fine. Check fuel pressure. Again seems OK. Test car and still won’t rev. Remove oxygen sensor from exhaust and run without incase exhaust blocks, but still the same. Disconnect Maf sensor and test. Car now revs out fine. Remove Maf and clean and blow out. Refit and test, OK now. Wipe over and test again, OK.”
