Not at all.
I have one, and they really enjoy revs, but should pull cleanly in any gear. There not fast with only 140bhp but there shouldnt be a difference with the engines performance in different gears.
Is it stuttering? this can be broken down/ wet leads otherwise I am struggling to suggest an answer,confused

Is it a 140 or 190 model?

Is the problem occurring at high or low revs?

If you're not going over 6000rpm then you're not getting the benefit of the 'L' bit of the VVTLi engine.

Next time you're out, boot it and see what happens.

Reason for the question is that the earlier engines were prone to faults with the lift bolts leading to sluggish performance above 6000rpm. If you've not been up that far though, then I suspect this is a different problem.

not above 4000rpm?

Unless the car is running badly (which i cant tell because i havent seen it) then i think you have found your problem. The 1.8 engine in the Celica is a very very peaky engine. All the power is in the VVTi zone between 6500rpm and redline.

To make good progress in this car you need to, for want of a better word, rev the balls off it. Which is a good thing! You wont break the engine by revving it, thats what it was built for!

The OP has a 140bhp Celica, not the 190bhp T-Sport/VVTL-i model.

No lift bolts (or lift cams) on the 140.

You guys are confusing it with the VVTi L engine. These dont rev much past 6500!



Could be something like a dodgy O2 sensor or clogged air filter, or dodgy spark plug.

When did it last have a service?
