Hi, took my n/a mk2 mr2 to get serviced a few months ago, and I think they mentiond that they retarded the timing slightly coz there was a slight pinking problem.

Since then the car doesn't seem as quick at high revs(and was still pinking until I added some fuel additive); I'm sure I used to get a bhp increase right up to the redline and a nice surge ovr 6000rpm.

Could this be a timing problem?
Is it easy to check the timing? I have no idea how its adjusted
