I pulled the whole engine out. The valve spring on #8 was broke. The outside of the spring looked good. Once we pulled the motor the back side of the spring is where you could see that it was broken. We had the torque converter rebuilt, replaced the broken spring, tune up. Put the motor back in...

I unhooked the ac & the heater has been working fine. I need to fill the ac with freon & hook it back up. My latest issue is that it has been making a rattling noise at start up. My wife says that it didn't make this noise before & it's getting louder. I started checking it out yesterday &...

I messed with the heater situation a little more. After reading through 2 hours of posts, I unhooked the vacuum to the heater valve on the passenger side valve cover. There's no vacuum going to the valve controller. I unhooked the actuator from the valve & opened the valve manually & now I have...

We've posted other threads about our original problem. Long story short, we pulled the motor & put it back in. We had a broken valve spring on #8. We put in a new torque converter, thermostat, tune up. Everything is workng great, it's running wonderful & problem fixed. New problem- there's no...

I pulled the valve cover & both valve springs on #8 looks good. The cam looks good. They both go up & down just fine when you crank on it. I don't know, there's definitely no compression. You can hold your thumb over the spark plug hole, crank it over & the air is going somewhere, it's not...

Today I took it to Ford to diagnose it. It cost me $217.00 to get a diagnosis. They say that there's no compression in cyllinder #8 & that both valves are stuck open. Ford wants to tear the head off & check to see if there's damage inside. They put a scope down inside the motor & they see that...

Yes I am mechanically inclined. My friend has a shop so we are going to pull the motor & take the head off & look at it, you can't get the head off without pulling the motor. Did this happen to you or do you have an 05 motor for sale? What motors can I put in this car that would work with my...

We've been having problems with our Explorer limited. It was running fine then driving down the highway, the check engine light started flashing. When I got off of the exit & came to a stop, I noticed the idle was rough & the car acted almost like if it's out of gas. I could put it in neutral...

Took my car & reset everything & tested it again. This time I got a P0308 code. So now the only code coming up is this. The other two are gone. I am wondering now if it's a crank sensor, which is what they suggested at the parts store. You can smell unburnt fuel out of the exhaust & it's missing...

Yes, they are individual coil packs & #4 has a hot blue very strong spark. The P0300 code is gone, we checked it on a different computer this time. The P0304 is the only code we got now.

I just checked the #4 coil. There's a nice blue spark that comes out of it which makes me think that it's not the coil. So, I started focusing in on the noise in the back of the motor that's been there since this started. It's a pretty loud "ch ch ch" noise in time with the motor turning over...

We installed the new pcv. No change. I had it checked on my buddies new computer at his shop. This time I got a p0304 code. A misfire for the #4 cyllinder. What's the firing order? What should I do?

I also installed a goodyear gator back belt.

found pcv I found the pcv. Its on the center of the passenger side valve cover. Its the screw in type. I went to the dealer to get one & they didn't have one in stock. We ordered it it will come tomorrow. u think mine is faulty cuz I can push & pull air through it with my mouth. Its suppose to...

Yes the picture is the 4.0 not mine. Thank you so much for your help. I'm just not sure where its at on mine.

I had under a quarter tank of gas. I stopped & filled it up & drove home & parked it in the garage. The next day mý wife drove it a long distance. It started doing it when she was about half way to her destination. She drove it home & I began to work on it. How would I know if it is the gas? I...

I completed the tune up. I replaced the plugs, air filter, fuel filter. Cleaned the MAF. Its still doing it. Where is the PCV located at? My vehicle doesn't have wires. Its an 03 but I think its the 04 engine because of the production date. Any more ideas? Thanks

I changed the plugs & it didn't help at all. It's still doing it. Next, I'm going to change the fuel filter & see if that helps. Any other ideas?

I was driving down I-5 today & the "check engine light" came on in my '03explorer. I got off the exit & noticed that when I came to a stop it was idling rough & almost shaking the whole vehicle. As I drove along, I noticed that if I put it into neutral at a stop & reved the engine, it didn't do...
