New to the 3.4...what to check?

[WideTrackGP_92]

I just bought my 1992 Pontiac Grand Prix SE with the LQ1 3.4 and a 5-speed manual transmission. The car has 171,xxx miles on it, so she's high up there. On the drive home from buying it, it ran and drove excellent, except for when it was at a complete stop, a few times it died, but fired right back up.

Anyways, I plan on changing the oil, flushing the trans and putting in GM Synchromesh fluid in, changing plugs/wires, new fuel filter, making a cold-air intake (or warm-air intake for now), getting new radiator, and checking the timing belt. Is there anything I'm missing that I should check on this car with this high of miles?

I would do a charging test on the alternator, check the spring insulators in the rear, check the intake gaskets for signs of leaking (oil or coolant) both are bad to have.... Recomend those when and if you have to replace the timing belt

Flush brake fluid, verify brake pads, rotors 'n' calipers are working and in good condition including the park brake. I'm convinced that power boosters are a common issue with these cars--but someone may disagree or prove me wrong. Assure that the ABS is working.

Verify all suspension and steering components are in good condition--ball joints, tie rod ends, PS works when the car is cold, struts, rubber bushings, etc. Flush PS fluid AND VERIFY THAT RUBBER PS HOSES ARE IN GOOD CONDITION AND PROPERLY CLAMPED. Look at tires for wear, especially symptoms of alignment issues.

Check fuel pressure; verify that the short-term and long-term fuel trim (block learn and integrator) are at reasonable values. Verify no stored trouble codes.

Check system voltage/amperage/parasitic drain/battery capacity including starter current draw--alternators are no fun to replace.

Listen for engine knock especially when cold. There's a known issue with the camshaft oil passages that causes lifter tick; and piston slap problems are common throughout GM.
