Suggestions on Cloyes timing chain kit Any suggestions on Cloyes timing chain kit? Are they trustable? Any other brand you would recomend that is not Motorcraft? Can´t afford their markup Thanks!

Update: replaced the battery and also fueled the vehicle with good unleaded fuel instead of flex fuel. So far it is runing fine. I will keep you posted. Tks!!

I'll do that first and let you know. Tks!!

Hi, I replaced the fuel pressure sensor About the timing chain, i had to remove the engine and replace all chains and tensioners. No additional engine damages were found. That was over 3 months ago. This surging problem started a week ago. Have not checked the fuel pressure. Do you think...

Engine surges at low idle and sometimes it stalls. No FC Hi, I am a bit lost and really need some help. My 2004 4.0 Flex Explorer is surging badly at low idle. Doesn´t do it all the time but when it does, it would even stall, especially when you shift to reverse or turn the wheels to one side...

hi, got a new problem with my 4.0 explorer. Started running really bad with an awful fuel smell. Had codes 300, 301, 302, 303, 316 and also 174. Seems all 3 cyl on the same bank missing. Any ideas? I also noticed the last couple of months a strong noise from the timing chain during morning...

it could be. What is weird is that when the light came on, I did not notice anything unusual, not even for second. In order to check the sensor and the hose, I'll have to pull out the manifold, which means that I'll have to order a new set of gaskets. I'll go ahead and buy the sensor since it...

forgot to mention that I used a bottle of injectors cleaner for the first time on this vehicle. That wouldn't have anything to do with the code coming up right? The engine is running perfectly fine, no misfires, no hesitation, no rough running, etc

So if the connector and the hose look good, should I replace the sensor? I check the FRP reading on the snap shot and it shows 515.001 Kpa. No idea if that's within reasonable specs. Tks

Reporting back.. Removed the MAF sensor, cleaned it well, installed it back and the truck ran well for a little over a week. No CEL came on. Today, out of nowhere, CEL came back on. FC 0193 by itself (fuel pressure sensor high input). Don't have the tools the check the fuel pressure. Any ideas? Tks!

Got it. I'll do that

I can do the first part but unfortunately my scanner does not show live readings, only snap shot of a triggered FC. Still, I'll check how the gauge behaves and get back to you. Tks a lot!

how can I check the Tstat setting or find out if it had time to reach its setting temp? A erased the codes a couple of times and the light seems to comes on during light acceleration. This last time I deleted the codes, just P0172 came back on. It seems to be an intermittent problem

53 Celcius. It would be 126 F

It was under cruising. Since I bought the vehicle from second hand, I am not sure the MAF is stock. Should I try cleaning the MAF sensor?

Hi, finally got the specs of the snap shot when the FC triggered. Please let me know if you see anything that calls your attention. By the way, FC P0175 was also logged, which is system too rich (Bank 2). So now we technically have rich combustion on both banks. Load PCT 60,8% Shrt FT1...

Haven't replaced anything yet. Shouldn't the O2 sensor trigger a code of its own? I have a snap on of the readings when the code goes active. Anything in particular I should look for to pint point the failure? Tks

What is confusing is that this started to happen a couple of days ago and I've owned this vehicle for 4 years already. If it was a recalibration issue, shouldn't have happened long time ago already? Tks

P0172 only, no other codes Hi, I normally use ethanol since this is a flex fuel engine, but right now it is running good unleaded fuel (95 octanes). Any thoughts? Tks!

Hi, pleasure joining the forum. I´d appreciate some help from such experienced people here. I am getting a code P0172 only, no 0175 or any other code. I am thinking this would not be related to a MAF or O2 sensors since it is only affecting bank 1. Any ideas? Tks!

Has anyone found out what could cause the P0172 only (P0175 not present). My thinking is that if I have a bad MAF sensor, the computer would trigger a code for both banks, noty just bank1. Also, if it was a bad O2 sensor, it should also read a code related to the sensor. Am I right?
