I have a 1994 jeep grand cherokee lerado which has had fuel pump problems, pcv elbow that was cracked, oil draining into my air filter and a leaking power steering fluid hose. During these I have had the engine light coming on while at high speed for an extended time. Also I can't pass a car on a 2 lane highway by simply just accelerating because when i go into passing gear i cant accelerate. Im not sure if any of the problems before could be related to whats going on now but no one can figure it out. This is my last option otherwise I will end up selling it.
