Hi, I have 2001 LS 3.9, it started misfiring after driving for a bit, I replaced coil pack on cyl 1, the light still comes on after driving for about 10 15 min. The car shakes anl loses power. I then replaced 1 trough 4 cylinder coil packs and still same problem with shaking and same 2 codes...

Just got code P1152, I wonder if it has anything to do with it, could it be faulty new Bosch O2 sensors?

Thank you for your response. The car had bad tensioner on bank 2 and stretched chain that was making noise. I replaced bank 1 and 2 tensioner and bank 2 chain. Also had misfires under load with no codes, replaced with new coils and running very smooth under all conditions except for 5 sec...

Hi, I have 2001 LS V8, when first started in the morning, after rpm drops from 1500 to about 900 the car starts to idle rough like misfire or like when doing KOER test for 5 sec and then rpm goes up to 1000 and everything is smooth. Also, I tried monitoring LFTR when car is hot at idle: bank 1...

Just finished replacing the chain, no more noise! Ran the car for 20 min and no noise, BUT now I have smoke from oil when it warms up. I don't see anything on the ground yet, but it looks like it's dripping straight onto the exhaust somewhere in the back. Probably something happened to new VC...

It has 102k, I got it from auction, it's in very good condition outside and inside, but it was barely running. I think it's original and lasted that long, I guess previous owner just didn't want to invest in it and donated it.

Hi, I'm going to try to replace to secondary timing chain on 2001 LSV8 this weekend. I had a broken tensioner and jumped tooth on drivers side, I replaced the tensioner and engine runs good, but after it warms up it makes rattling noise. My question is how do I remove old chain without taking...

So I replaced both tensioners and the car is running really smooth now, no missfires no codes. BUT, when the car warms up it has a rattle that seems to be coming from drivers side where the tensioner broke. It doesn't do it when the car is cold at start up and also when you rev it it goes...

Thank you, I'm going to replace plugs anyway, might as well take them out. And if the flats don't line up, do I take the chain off and move the cam so it lines up?

I edited the post to correct my mistake, i originally wrote p0701 and p0705 by mistake and I'm not sure why I did it.

The codes are P0171, P0175 and P0307. I just wanted to know how to find out if the car jumped timing. Joeger: thank you for your answer and shop manual. Do I have to remove spark plugs before I turn the engine by hand and try to align the flats? The car was running but very rough at idle...

I'm sorry i posted wrong codes, I don't know where I got those from lol. The actual code is for bank 1 too lean and bank 2 too rich.

Hi, I have 01 lincoln ls v8 that I just bought. It has codes P0171, P0175 and P0307. After doing some research it led me to belive that secondary tensioner broke and possibly jumped timing. I took both valve covers off and found that drivers side chain was riding on metal part of the...
