Hi all as you might have seen in show and go i`ve just finished a paint job and engine rebuild,any way got a permit to give it a drive but it drives like a pig.
big dead spot off the line dead,dead spot at 2000 rpm,bunny hops etc sink the boot in and it goes good.
the only way to drive it is rev the shit out of it off the line and keep the engine away from 2000 rpm.
so what to start at ? injectors?,afm?,tps?,map sensor?ecu?
and has anyone got spec`s to check these items
regards Mackaman
problems
Yes. All the above.
In particular, check the output from the TPS, just hook a multimeter across the terminals, open and close the throttle and make sure you get good and continuous resistance readings.
Then...unplug whatever electrical connection you can and clean with a small file, sandpaper, whatever and contact cleaner.
Have you changed fuel filters? Has the car been sitting for a while with fuel in it? May have crap or varnish partially covering the fuel pickup.
Enough to start with?

Pull the fuel pickup out of the tank, the basket at the bottom may be gummed up from sitting fuel.mackaman64 wrote:yep replaced filter new fuel pump fitted 1 year ago but no use since then
fresh fuel,had a look at the connections but all looked clean no green corrosion,can we get a new tps? or one from another Mitsubishi , can check fuel pressure
Just check the tps output, no need to replace if it's working ok.
Check your email too.

You will need to pull the fuel tank and clean it, change the fuel filter and make sure the basket on the fuel pickup in the tank is clean.neil wrote:Excellent news - and good to know - my JD has been a static ornament on the nature strip for the past 2-3 years so I know that this is a job I really need to do before its GO time (whenever that may be - could be another 3 years at the rate I'm travelling.... )
