4.0

I know this question has been asked a lot but I need help. I bought this exploder and it has a hard start situation most of the time and check engine light with the infamous lean bank 1 and 2. The hard starting is random, sometimes it will start right up after sitting overnight. Temperature...

I have a 2003 XLT 4.0 SOHC V6 with 210,386 miles on it. The engine starts up great but makes a loud ticking sound. I'm assuming it's the hydraulic lifters and that they are gunked up. The sound usually gets quieter when the engine is warmed up, leading me to believe that it is quieting down...

Been trying to get to the bottom of a bank 1 misfire. Actual codes are for cylinders 1, 2, 3, and random misfire. All happening at different times. Car seems to run fine until 45-50 mph and trying to accelerate, maybe somewhat of a lumpy idle, and/or odd lumpy acceleration. Doesn't feel as...

A family member had noticed that it looked wet in a specifc part of my engine while we were taking a look and refilling the coolant. I had noticed something similar a while back, but I was foolish and thought it was just rain. I think that was a mistake :P I use 50/50 coolant and the level...

I am in doing my thermostat housing and figured its a good time to replace the timing chain spring tensioner on the left bank front since I have access to it. My question here now is that the is a pinhole in the tensioner and a 1/4" hole in the thread area for it in the head. I do take it that...

Hey guys. I recently picked up a 2002 Explorer with the 4.0. It had been wrecked but otherwise ran and drove. I replaced the radiator, fan, fan clutch, and water pump (all damaged in the impact). While replacing the water pump, I removed the thermostat housing to give myself room. So I...

I have 2001 Ford Explorer Sport Trac 4.0. I was driving and my oil pressure went all the the way down and shut it off. I was wondering if they was a sensor that makes it shut down when it loses oil pressure. Thanks
