98 explorer sport (power loss)

Hey everyone. I'm just wondering if anyone knows , or has had the same problem with their explorer that i'm having. My Explorer sport is surging when at a constant speed and feels as if it has lost alot of power. I changed the wires since one was cracked, but it still does it. I'm just looking for a few ideas about what maybe it should be, since i have to sink another$400 into it this week for a hub assembly.. Any assistance would be greatful..

Thanks Jay

Clean your MAF, IAC and throttle body. Make sure you use varnish safe throttle body cleaner on the throttle body and 02 safe cleaner on the MAF. May want to check the serpentine belt for slippage or looseness. Lastly, make sure you disconnect the battery while doing the cleaning.

Jay ,did you have it scan for codes within the computer ?
some times codes will be posted even if no chk eng light comes on!

All of the above posted was correct ,you could be developing leaking
lower intake o-rings also.

Just my opinion

Your MAF is located at the end of your air intake tube(oposit the throttle body). It is the flat black box right after the air box. The IAC depends on your engine. On my SOHC it is located on top of the engine under the "SOHC" cover.
