UPDATE. ...Thoughts? I've just checked the fuel filter...clean as a whistle. My crappy Summit fuel guage in-line just before the throttle body was reading 11 psi until i reved it up and it dropped to 3psi. Not trusting it I put a Snap On gauge on it and it reads 12 all the time idle or 5000rpm. When hot after 5 mins of hard driving it still read 12psi but was 'fluttering' a bit but still constant. I gave it quite a hard drive and all seems well! Which is a PIA as I haven't done anything so it could come back at any time . So was I just unlucky and the FPR stuck for a bit? TPS or MAP had a mad moment? I wouldn't have thought they have 'off' moments....thought that was just women!! Any thoughts gratefully recieved! The '90 tbi motor in my '78 has just starting acting like it's getting real bad fuel starvasion. I just had to drive it home on a very light throttle and low revs. Try to open it up a bit and it just dies and bogs down, sounds like the motor actually cuts for a moment. As soon as the revs drop it picks up again. No popping or banging so it seems very fuel related rather than electical. Too busy at work to look right now but I'll check the fuel filter and lines as soon as poss but has anyone else had this or can suggest other sensors that might make it do this? Everything is new inc. in-line pump, filter, hoses and a rebuilt TB unit. Maybe my tank is just so rotten inside it's fouled up the new filter already!! Any suggestions? Thanks.
