ford ranger 4 cyl. 2.3 ltr. automatic
i have a 1996 ford ranger 2.3 ltr. 4 cylinder, i changed the head gasket [blown between 3th. and 4th. cylinders] engine idles very good but loses speed going up hill [no pulling power], ijust checked the timing belt again every thing lines up with the correct marks. i also checked the fuel pressure [engine off key on 45 psi. engine idling 35 psi.], compression [ 175 psi min. ] i also checked the plugs [new and at correct gap ] i changed the coils and wiring. checked for vaccum leaks [none found ] can anyone help or have any ideas what i can look for that might help fix this problem.
