1998 Explorer, 4.0 pushrod
Been driving this vehicle for almost 5 years. Check engine light has always been on but always started and run good.
A couple of days ago it started running rough above idle and very little power. Could not rev the engine above about 3000 rpm. Starts and idles like always. I changed the spark plugs and fuel filter. Made no difference. TPS voltage is a bit high at idle, 1.14 V. 4.46 V at WOT. I can hear the fuel pump running. I will clean the MAF sensor and pull codes Monday.
Any suggestions?
