Hello. I'm new to the forum. I have an 82 CJ7 with a fresh rebuild 258 and the Hesco MPI installed by myself. At low power the engine runs fine. But under load, say going uphill or when giving a sudden throttle input in a higher gear, the engine begins to misfire or cut out as though one or more cylinders are not firing. If I ease up on the throttle it recovers. If not it shudders pretty bad until I do. If I go easy on the throttle the problem does not occur. Only under load. At cruise speed on the freeway it mostly runs good, but occasionally I do feel a slight power loss as though I am dragging a cylinder. The plugs are clean so I don't suspect an ignition issue. It acts like its running out of gas. Thoughts or suggestions much appreciated. Lou
Hello All, This is my first post and hope for the best. My 1990 YJ Wrangler Jeep 2.5 TBI starts well in the morning, heats up to temp and can ride for about 35 minutes. After which it starts to act as if it wants to turn off. If I step on the gas it kind of coughs. What I do is pull over and while in neutral it turns off by itself. I wait about 10 minutes, turn it on and we’re almost back to normal, just enough to make it home. If I wait longer it turns on and drives well. Thanks for your help.
