Hi folks, New to this forum.
Just bought my teenage son a 95 TS, Auto 2.6l. Goes like a charm, runs smooth, starts first time, hot or cold.
Problem is, when we start on a slight to mild incline or accellerate up such an incline, the motor seems to starve for fuel, revs drop, speed drops to about 20-30kmh. You can relese the throttle and reapply, no change in performance.:wtf:
The previous owners said they will get their mechanic to look at possibly the vacuum? or the carby in general.

Any ideas, as we live on a mountain (Toowoomba, QLD) there are a lot of hills to get up and down. Is there a magic fix, or do I have to wait for the previous owners to contact their mechanic ( son impatient, as teenagers are)
Thanx.

Check your fuel filter isn't blocked and that all vacuum hoses are connected / not perished / holed etc. My sons TP wagon had a similar problem it turned out to be a combination of split / perished vacuum hoses, a leaking / not holding vacuum secondary barrell diaphram on the carby which prevented the secondary barrell circuit operating. The vacuum advance diaphram on the distributor may also have a leaky diaphram.
Any vacuum leaks will directly affect the carburettors ability to supply fuel to the engine.

Cheers

all of the above .... and ........

may be clogged carby jets

does the auto kick down and shift up as it needs to

Fuel pump. Block off the return line ( either by bending or a clamp) and see if it improves.

another Toowoomba Magna owner to add to the club ;-)

I bought a TP with carby 2.6L years ago with the same problem. It needed all of the vacuum lines replaced - just buy 2 m of line and replace them all, one at a time so you don't hook them up wrong. It also needed the automatic choke to be backed off as it was staying on. I reset the ignition timing and it ran like a dream after that. I got it cheap because the engine made some grinding noises at startup like the chain guides were dead, but it turned out to be the starter motor reduction drive disintegrating. All worth checking.

Thanks guys for the great advice.
few points:
Fuel Filter is new and seems to be working properly
Auto Kickdown is functioning properly
I will buy some vacuum line and replace the old lines (they do look perished in places, might be some cracks as well)
I will also check the fuel pump.

Again, thanks guys and I will post the results of your advice.
