90 3.9EFI by your profile?

How about the car electrics - do they disappear when turning? If so, check the battery connections and it's earthing.

Something electrical - corrosion or bad connection somewhere. I'd first check coil and the connections there (especially the white/black wire at coil negative feeding the ECU the engine speed signal). Then I'd check for the distributor, connections, leads, cap, rotor and any excess play there. Then the AFM and its connector. Then ECU earthing at the behind of the odd bank head.

Should it be fed by carburettor, I'd suspect flooding.
