    1991 L98-At WOT engine boggs down and nearly stalls.

    Up date I installed the new ACCEL injectors I ordered from Summit after OHM checking them first to make sure they were in spec. Its a major job for an old guy who is used to a carburator. The car now runs like new. The whole problem was 4 bad original injectors (20,000 miles) that should have...

    1991 L98-At WOT engine boggs down and nearly stalls.

    I am going crazy with this problem! It has been to 2 shops and neither can figure out what the problem is. When you stomp on the gas to WOT the engine boggs down and nearly stalls. It gets so close to stalling you think its going to any second and never does. There is no check engine light or...
