gu power or lack off
gu power or lack off
hi all i have a drama my 4.5 gu has this on and off problem a little info it has unchip and full exhaust sys and duel fuel now just the other day driving down the road she had a miss fire and went away but then i went to go around a car it just died it ran out of power and could not rev up and could not even rev past 3000rpm i have been under the bonnet for the last two days going over eveything and all looks fine so i was thinking it is the dissy playing games??? can anyone else give me advice anything would be great thanks
He should have. It could certainly be ignition, if worse on a snap throttle and high load that might point to a leads breaking down or jumping to ground. Also make sure the top hose is not rubbing against the leads. Check all the obvious stuff if you haven't. Cap, rotor, plugs, leads. Also the intake manifolds can get air leaks at the joints.

If it backfired, It may have blown the " SEAL" that is the failsafe to protect the airbox/mixer during backfires.. check the intake hose from the airbox to the intake manifold, you may find something like wesuit material, or a bit of gaffa tape thats blown up.
you could have also blown the airflow sensor or covered it in crap from the backfire.

mine has something similar at 3100rpm. the power seems to "kick in" noticably above that.
is this similar to your old one?

Not really on petrol, but thats what it did on gas. Above about 2500rpm and it felt like it had an extra 30kW kicking in...j-top paj wrote:nabstud wrote:My old 4.5 GU did something sort of like that, it also had a flat spot.
