TexasZR1 · 10-20-2018

Well... typed up a long introduction and got auto-logged out... a sign it's TOOO long I guess.

Short, simple version: I bought a 1990 ZR1 about a month ago. blk/blk completely stock (does have AT LEAST skip shift eliminated) with 53k miles.

Love the car.

Long time GM fan with a small stable at present: 1994 turbo diesel suburban, 1991 Camaro z/28 5sp B4C (police package) and a 2013 GMC 3500 diesel.

Plan on resolving some minor issues with the car (wiper motor, suspension control module sometimes pops light, AC shutting off / req. battery reset, worn out rear speakers, and?? what do they usually NEED at this point?

Also considering some minimal upgrades: C5 front brakes, Long tube headers and cat back and maybe a set of NT555R's?

Nice to meet you all!

Welcome Tanner!!
There is a good checklist of common issues on the ZR-1.net site. Below is another good list of things to check that one of the members posted.
If you have any issues, reach out here in the forum and you will get knowledgeable advise.
Used ZR-1 Evaluation Checklist (via Hans Meyer)
Injectors
Vacuum leaks
Secondaries operable
Ingnition coils and wires replaced
Timing chain noise (normal to a small degree on 90's)
Starter
Oil leaks especially the pan and oil cooler lines
Fuel pumps
Is it throwing any engine, abs or body codes (multiple possibilities here)
Are any DIC lights on. (Multiple possibilities here as well)
Is the adjustable shocks system working
Windshield delamination
A/C functionality (compressor is unique to the Z, cooling capacity lower)
Power switch functionality and keys (are there 2)
Transmission syncro's, (first gear is always noisy) shifter alignment can mimick synco problems.
Clutch functionality (they all let in high, was it ever changed)
EGR system on later models
Engine mounts

C4 Issues
Head lights operable
Radiator blocked or simply clogged, electric fans operable
Wheel bearings
Suspension bushings
Condition of all door, top and hatch seals
Glass roof cracking
Instrument cluster functionality especially the tach (tends to read high with age) also note the lighting of the cluster.
DIC button functionality
Steering wheel excessive movement
Radio functionality (especially speaker amps) and antenna
Sport seat functionality (transmission, switches, pumps and bladders)
Door window switches
Door window lifter and internal rattles
Fuel tank bladder collapse (results in small capacity)
Differential noise (whine)

Have fun with your new ride!!
