Vibration under acceleration/Loss of power - ZR-1 Net Registry Forums

Hey everyone.

New to this forum.

Picked up my 1992 ZR1 in early April this year. Had its safety done and emission tests here for Ontario Canada. Everything passed.

My LT5 has just over 4000 original miles. I've put about 100 miles on since Friday. Today we went for a 25 mile ride, on the way back...after about 21 miles....I tried accelerating in gear 3 at around 30MPH and the whole vehicle vibrated during acceleration. The RPMS were around 2500. Tried it in other gears and same thing. Turned on the power valet switch, same thing. I do notice a power loss when this happens.
Service ASR and Service ABS lights have been coming on intermittently and will shut off after the engine is shut down and restarted. No other lights are on the dash display.

I don't have a testing tool yet, wondering if anyone has had this experience and what it could be?

Thanks

Paul
