stevenwham Posted April 18, 2022 Share Posted April 18, 2022 Found a beautiful Super 88 - after owning about a week, on a cruise on a deserted country road, decided to "open it up" & see how it would accelerate .. accelerated fine BUT accelerator stuck full open .. initially applied brakes; that didn't help .. as I'm gaining (too much) speed, I shifted from Drive to Neutral .. that created alot of "racket" & I decided that wasn't good (in hindsight that may have been fan belt screeching), so then shifted back to Drive & that seemed to go okay .. then decided to reach down and "unstick" the pedal .. that worked, but the pedal came off in my hand, but I was able to slow the car down & got it home okay .. (pedal on order) .. the next day trans seemed fine until cruising in 4th gear (acceleration through all four gears is fine) at stable throttle, there is a subtle "lurching" in the drivetrain which I would guess is something amiss with 4th gear .. would appreciate your thoughts .. trans was overhauled during restoration 20 years ago, but has minor miles since then .. thank you Link to comment Share on other sites More sharing options...
JACK M Posted April 18, 2022 Share Posted April 18, 2022 That is one nice Olds. It's funny what goes thru our minds in a quick emergency. These days you can't just turn off the ignition as it will lock up the steering. 1 Link to comment Share on other sites More sharing options...

TerryB Posted April 18, 2022 Share Posted April 18, 2022 Did something to create a lean running condition that is noticeable at cruising speed? 1 Link to comment Share on other sites More sharing options...

TerryB Posted April 18, 2022 Share Posted April 18, 2022 Check you rubber vacuum hoses for loose/cracks too. 1 Link to comment Share on other sites More sharing options...
Oldtech Posted April 19, 2022 Share Posted April 19, 2022 Probably engine, not trans. The engine may have over-rev when you took it out of drive. Could have a bent pushrod or even valve - or a broken valve spring. 4 Link to comment Share on other sites More sharing options...
NailheadBob Posted April 19, 2022 Share Posted April 19, 2022 I would agree with @Oldtech I would remove valve covers for a visual inspection and see if any loose/bent pushrods or visual broken valve springs, if all looks ok do a compression test and a leak down test next.

These days you can turn off the ignition without going further on the tumbler to steering wheel lock. 2 Link to comment Share on other sites More sharing options...

nickelroadster Posted April 22, 2022 Share Posted April 22, 2022 Before 1969 cars did not lock their steering wheels when the key was pulled. 1 Link to comment Share on other sites More sharing options...

nickelroadster Posted April 24, 2022 Share Posted April 24, 2022 That is when it became standard practice to do that Link to comment Share on other sites More sharing options...
