Hi, not sure this is OK to post here, so if not please delete. I started my 93 Supra NA auto after about 3 months and it started straight away, no issues. But then, without any input from me, the revs to shot to 2000rpm and immediately drops back to about 1400 and repeats this all of the time like someone is blipping the throttle all of the time? I let the car do this for about 5 minutes with no change in the blipping, so switched off and back on, but it still did this. I looked at the exhaust but couldn’t see anything out of the ordinary. To note, the car was put away 3 months ago, without any issues and I haven’t touched the car during this period. Oh, I did drop the car into reverse and held it on the brakes and then the revs sat at a steady 2000 rpm. Any idea what could have happened whilst it sat for those months? Many thanks.
