'94 4.0L Ford Explorer losing power

As I'm driving my '94 4.0L 4WD Explorer down the highway, it vehicle will start to lose power, and lose rpm's for a few moments, I slowly pump the gas and the rpm's return to normal. This happens about ever 5-10 Kms. Thinking maybe the fuel pump is getting weak, already changed the filter and switched the fuel pump relay fuse, and they weren't the problem.

Shouldn't cost much for 10 minutes work to test fuel pressure & confirm pump condition, but do it when vehicle 's been running for a while, long enough for pump to get heated up.

If you have a manifold gasket leak on a '07 trailblazer ss would it make the vehicle lose power when driving down the highway


A manifold gasket leak will cause a power loss everywhere you drive, although a hot engine may lose more power than a cold one. You can check you spark plug color. A manifold leak makes a lean mixture so the plug should show the typical white-ish deposits.

IN most codes recorded there are a list of possible causes for example if he said possible crank position sensor=== there is also the cam position sensor --wiring --ECM--HO2S sensor --MAF/MAP/VAF sensors that come into the equation

2000 ford explorer 4.0 x-engine is stalling, missing and lose power while driving


I personally would check the fuel pressure. Then I would go back to the coil. I have seen brand new bad coils out of the box. The symptoms of a loss of power point to this component, especially if the car idles well, but loses power when accelerating. Please do not rate this reply - we all are left to grasp at straws since you have changed pretty much everything. Good Luck. Please post the final fix of the problem.

Most likely your oil pressure relief valve located on in or nearby pump. Symptoms are oil pressure will drop when warmed up when idle lose all pressure eraticly giving the vehicle gas will bring back pressure and highway driving will bring pressure up until idle again.
