Ok I got the car last year and drove it back from Florida. It's always had this motor, tranny, or exhaust thump that similar to the heart beat of a helicopter. At idle it’s as smooth as my 90.
Since then, I've replaced the (broken) motor mounts, (warn out)tranny mount and bushings, rebuilt the (nasty) injectors, resealed the intake with new gaskets, replace the radiator (that had a hole in it) and the thermostat (that would only open a 1/16th of an inch).
I also installed a new SD coil, NGK Iridium sparkplugs, taylor wires, cam sensor, IC gaskets, and a under drive pulley set.
I have no CEL and I ran a computer balance test on the motor (and it passed). Outside of my blower maybe needing a new coupler (there is a little slop in it), the shiffer chatters a little a low speed so I'll have to rebuild it this fall along with the blower.
I have an SPC upper exhaust system ready to install but the Bill accidentally send me a drivers side down tube for a 89-93 so that's on hold for now.
I have a receipt where the clutch was done about a year prior to trading it to a dealership.
I'm stumped about the heart beat noise. The car pulls better then my 90 but dogs a bit unless I up shift from below 1.2k rpms during 3/4 throttle. This and the heartbeat keeps me from driving it as much as I do the 90. It's so much smoother but it has an AOD.
Anybody have any ideas?
