4ze1 lose of power

[boganracing]

hi as of a few days ago my 2.6 rodeo has lost a heap of power its not to bad on the flat but on a slight hill it will slow right down and i have to drop it back a gear or 2 these hills i used to be able to cruise up in 5th but now its sluggish as hell, and on the high if i put my foot down at 80 it will barely accelerate on the flat and no chance on speeding up even on the slitest hill, anyone got an idea of my problem?

my mate had the same problem found it was a collapsed cat converter he smashed the centre out, he found that was his problem.

hope that helps buddy

yea exhaust sounds like the culprit, i have had a fair few 4z's in the past and they generally are pretty good, little things can go playing up (eg tps, airflow meter) but these generally cause surging or engine shutdown

i would be also replacing the fuel & air filter

cheers

turns out the guy who last did the timing belt put the crank gear on backward which wore out the key way which created a lot of movement in the timing gear so timing was moving from acuarate to about 20 degrees out and back again got a new gear and key way and car has been fine ever since thanks guys
