hey guys, i drive mums AU TE50 sometimes and have found that it is really sluggish down low, like really bad (only sometimes/rarely spins em off the line). the motor was rebuilt (standard specs) and i think and hope that it is still on the run in tune because it used to perform much better than this before it was rebuilt. once its moving its alright, but i think that there is more in her thats not coming out. can someone recommend anyone in sth eastern suburbs in melb that i can take her to, to get a tune?? thanx

try different fuel. it might be that the compression has increased and it will run heaps better on 98 octane. try it with a full tank of premium before you take it to somewhere

maybe it was not the engine that had to be fixed (as you said that it ran better before it was rebuilt)

maybe blocked exhaust sytem??

as for fuel, i recommend BP ULITMATE

when you say rebuilt to standard specs you mean tickford te-50 specs dont you? What actually was done to the engine?
was the cam changed?
get detailed work that was done and take it to a good dyno man and they will tell you exactly whats happening. :)

the maf is bolted directly to the top part of the air intake box and the plug is located on the side closes to the engine 4 wire plug. if it isnt plugged in it will not idle correctly and guzzle fuel as well.

I'd say the cam sensor is out giving you some retardation. A common drama with AU windsors. Ford have the know how here assuming this is the problem.
