Hey guys,
Ive got an xh xr6 ute,manual but its got an issue when its cold. driving it will hit about 1800rpm and it just hits a big flat spot,change gears n thent he same thing happens from around 1800-2500 but if i give it more gas it will just take off like it was never there.
Once it warms up it goes away,Im a bit lost with this one.
Ive changed leads and plugs also an injector clean,always run on good fuel.

Thanks
