Hey all,

I have had this problem for a while... but really getting on my nerves.
Going up a hill, the car struggles to move. Even worse when the A/C is on... Only just manages.
I have changed and checked so many things. Dont know where to look anymore...
Any suggestions?

Cheers

how old are the plugs

water in the fuel tank ..add some metho

I have changed the plugs, leads, fuel filter, fuel pump, coil, checked the distributor cap and rotor. I have had this problem for many months. It use to run a lot worse. Would cut out and hesitate a lot. New pump and filter fixed it except uphill it just chokes.

Same with my TR, itll go up most hills fine, but when i took it throgh the adelaide hills it was missing heaps, iirc i was maxing out flat to the floor at about 60... not good when its busy :/

Dirty injectors is where I would start if you have looked at everythign else including fuel flow, pressure etc etc

To be perfectly honest I would need to see the car as there are a couple of other things I could check as well

Ignition coil and/or power transistor breaking down under load.
Blocked catalytic converter/exhaust.
Low compression.
Ignition timing.
And the usual suspects - blocked injectors, low fuel pressure, old fuel filter, blocked air cleaner, distributor cap, leads, plugs.

First thing I did was get the injectors cleaned. Was praying there was some dirt in my injectors... but no luck :(
I have checked most of what you have mentioned. Think Ill let you take a look at it MadMagna.
Ill pm you soon.

Thanks again guys
