Cannot Reach rpm redline Options

[Chung_hk]

Hi Bros,

I'm from HK, I'got a problem with my Celica 3SGE engine, it cannot reach the max rpm when running at any gear, and even just stay. The rpm grows without any drops or lacking power till 6000 rpm. It stops there, just like reaching the max rpm limit. I renew the old sparks plugs with Denso 16, and and ignition chord with TRD.

Some car repair service suggest to check the distributor, but some claim that's the problem of rpm limiter/ O2 sensor...

So do u know which part I can check and follow?

Thanks!

I would also suggest looking into the cam/ignition timing aswell, get a timing light.

Is the car throwing any cel's at the moment?

I used timing light to check it at idling speed of ~800 rpm, it's around 7-10 degrees, it seems normal. isn't it?

But one thing, I've found the coolant temperature raised very slowly to the normal operating level since starting engine, may be more than 5 minutes. Will that cause the engine stops at 6000 rpm?
