[dunga70]

was running fine then bang! someone stole my power?
its slower than a stock 4k now.. i think the tps was playing up could that be it?
its still running on all 4 cylinders but wont go anywhere?
any ideas fellas?
cheers

more info please.

[dunga70]

It runs.. U put ur foor down and it doesn't go anywhere.. Was working fine The just died in the ass. The distributor is leaking oil but doubt it has to do with that.. Thinking it could be more the throtle position sensor which i was told is worn out which makes my idle fluctuate ?? What other info u after?

does it still rev?

[dunga70]

It Revs in neutral.. Not quite as quick as normal. And has abit if a splutter on the way up and a cough in the exhaust in the way down.. When driving it revs but takes forever

ok so under load there is no power.

- quickest way to determine if its your TPS is to loosen it with the engine on and move it around to see if the revs change, if they don't then you have a TPS problem.
- if the the revs do change then it could be timing related.
- check inside you dizzy for excess oil. if none then its just the shaft o-ring that needs replacing.

fuel pump

^ good point. no pressure could explain the hesitance and spluttering. if its running lean the exhaust cam cover will be alot hotter than the intake.

[dunga70]

The fuel pump runs... It makes noise? So mayb it's internally fucked and not making pressure.. Could also be why it idles rough?

do a comp test?

id check the plugs, leads, cap and contact
