My Supra Is Starting To Splutter On High Rev

[DAZ16]

My Supra Started To Splutter Like Hell The Other Day, I Took It Into My Garage And Discovered I Had A Fuel Leak. I Repaired It And Now Its Only Spluttering On High Accel.
The Cars Running Smoothly While Just Cruising......

Sounds like it could be a duff o2 sensor. :search:

Any1 Able To Give Me Advice???Yes, turn off your Caps Lock.

Sounds like it could be a duff o2 sensor. The O2 sensor is only used for closed loop though Jez, isn't it.

I'm just going on experience of a missfire / splutter on my old car at higher revs. I changed the 02 and it cured it. :search:

[DAZ16]

cool, i'l try the plugs first

[Markie]

Has started just all of a sudden? Like parking it one day all fine then the next spluttering?
I have similiar problem at the moment.

Check coil pack connectors first before you take the plugs out and change them. Is cheap to change all, failing that then you could try soaking the O2 sensors in lemmon juice etc or change that and are about £80 ish.

Gap the plugs to 0,7mm and see if that doen't help.

The O2 sensor only has an effect on fuel in closed loop, so anything over 4000rpm it may as well be sat on a shelf in the garage for all the influence it has.
