The 1982 L83 was again the only Corvette engine, producing 200 hp (149 kW) and 285 lb⋅ft (386 N⋅m) of torque from 9.0:1 compression. Since GM did not assign a 1983 model year to production Corvettes, there was no L83 for 1983. [22] This was also the only engine on the 1984 Corvette, at 205 hp (153 kW) and 290 lb⋅ft (393 N⋅m) of torque.
LS2 can also refer to the 1973–1974 Super Duty 455 cu in (7.5 L) Pontiac V8 engine LS2 can also refer to the 1985 Oldsmobile Diesel V6 engine. The LS2 was introduced as the Corvette's new base engine for the 2005 model year. It also appeared as the standard powerplant for the 2005–2006 GTO.
Other problems may be implicated in the case of older vehicles equipped with carburetors. Weak, disconnected, or mis-connected throttle return springs, worn shot-pump barrels, chafed cable housings, and cables which jump their tracks in the throttle-body crank can all cause similar acceleration problems.
Diesel engine runaway is an occurrence in diesel engines, in which the engine draws extra fuel from an unintended source and overspeeds at higher and higher RPM, producing up to ten times the engine's rated output until destroyed by mechanical failure or bearing seizure due to a lack of lubrication.

Lift-off oversteer (also known as trailing-throttle oversteer, throttle off oversteer, or lift-throttle oversteer) is a form of sudden oversteer.While cornering, a driver who closes the throttle (by lifting a foot off the accelerator, hence the name), usually at a high speed, can cause such sudden deceleration that the vertical load on the tires shifts from rear to front, in a process called ...
The intake manifold vacuum, with wide open throttle, is lower in these conditions, which causes the PCV valve to open and the crankcase gases flow to the intake system. [13] The greater flow rate of intake air during these conditions means that a greater quantity of blow-by gases can be added to the intake system without compromising the ...
The 2020 Corvette C8 was the first Corvette to have a rear mid-engine configuration, [108] GM's first since the 1984 Pontiac Fiero. The base Stingray coupe was introduced on July 18, 2019, with three launch colors, red (with the Z51 Package), white, and blue, and the convertible on October 2 at the Kennedy Space Center , joined by the C8.R race ...
Wide open throttle or wide-open throttle (WOT), also called full throttle, is the fully opened state of a throttle on an engine (internal combustion engine or steam engine). The term also, by extension, usually refers to the maximum-speed state of running the engine, as the normal result of a fully opened throttle plate/ butterfly valve .
