[SURTEESS]

Looking for injector cleaning / flow checking for a friend on mine on his MR2 here in Auckland NZ.

The MR2 (Turbo) has a "misfire" around 80-90kh/m, change down to get past that speed & then change up & all is ok ???? been that way since Xmas.

We have also drained out fuel & added 95 (just to make sure that mixing 91/93/98 over the past 3 months was not the issue). Also changed fuel filter & done lead changes for injectors...it's still there.

North Shore Toyota have had a look at it "there is nothing wrong" - in there own words !!!!.

Any help would be great.

thanks
