I have a '93 Pathfinder. When I'm driving down the highway and I take my foot off the gas the engine "lugs" and misses. When I reapply the gas it won't accelerate unless I really step down on the peddle. It's now doing it driving around town (low speed). It will do the same lugging, pulling away from a stop light until it gets up to speed then it's fine. Any accelerating or decelerating causes the lugging and misfiring (popping sound in the exhaust manifold). Is it something in the fuel injector circuit? Fuel pump?
Thanks for the feedback
