Having problems with my VVTi engine

steinooo · 17 Sep 2009 at 22:24

On my Gen 7 Toyota Celica.

There isn't an increase in acceleration in the higher revs range (bit like vtec in a Honda) like there was in my last Celica, anyone got any ideas please?

I have no engine management lights on. The only thing I can think of that I havn't tried is to clean the mass air flow sensor, but it sounds like a long shot to get it working.

thanks in advance if you can help.

140. I've replaced sparks, air filter, oil filter and oil and the problem is still there.

It definately should have a kick though, my old 140 did, and I know other people's Celica 140's have this kick

i'm positive my old 140 had a noticeable difference in acceleration though.

lol, i would begin to doubt myself now but a chap who works for toyota on the owners club agrees there's a difference in acceleration, albeit less so than in the vvtli

Nickg, thats a good website that, proves that perhaps I'm fantasising about my old car!! :confused:

Rackerz - I'm pretty sure I thought vvti made a difference to revving at about 6000 revs but not sure what it red lined at. I'll get some of this MAF sensor cleaner i've seen on the auction site and spray some on, it can't hurt I suppose. Feel a bit glum tbh!

Nickg is right, 190 Celicas in the UK are VVTL-i spec. However as proved, maybe I'm not the best person to comment on the technical aspects of Celicas!
