New member here ,fisrt post . I own an 85 gsl-se with no major mods other than exhaust . The car runs awesome just jerky when letting of the gas and getting back on it again . Its almost like it doesnt coast well . Is this just the gearing in the rear ? Thanks Paul

shouldn't be the rear end but it could be a lot of things......it really could be anything from the engine leaning out to the clutch slipping.

anyone else have any ideas?

I dunno. Motor/transmission mounts?

Idle/decel issues? TPS?

Like you say, could be most anything.
