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! -Tanner |

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!! ![]()
