Hi New to site and have a problem with my P38 not revving

Ian1151 · Aug 9, 2012

Just fitted an overhauled 4.6 in my P38, started fine and runs smooth upto about 2500-3000 RPM then it starts missing as if there is a rev limiter stopping it. Could this be the case or anyone got any ideas. Thanks

Can't they be stripped down and sprayed with carb cleaner on landys ?

You could just spray carb cleaner like you say but if found it to be more sucesful if you put the maf in a plastic bag and let it soak in carb cleaner for 10-15mins then take it out of the bag. give it a quick wipe over then leave to dry for 24 hours in an airing cuboard. worked everytime for me
