Hi I have Peugeot 307 SW 2.0 litre diesel (2003), engine - DW10ATED. Time has come to replace a timing belt. I would like to do it myself. Read through many forums but no exact work instructions could find. Read through Haynes manual but if I follow it, I would have to take half of my car apart just to replace a cam belt (i.e. remove whole exhaust system as if it is not removed, the front pipe flexible section will be damaged when the right-hand engine mounting is detached). Looks strange, bec

My car is having difficulty idling, this morning it died on my way to work but started right back up. The check engine light has been on for about 3 weeks. I took it to a garage to have it ran on the machine, it came up with code P2187 Lean O2 sensor on bank 1 and bank 2. I was told that cheap fuel can cause this code and the guy pretty much told me it wasn't worth fixing. The car is having trouble idling, but the guy said if I replaced the O2 sensors it would pretty much just do the same th

A diagnostic test showed I have both System Lean Bank 1 and System Lean Bank 2. There is also a burning smell coming from the passenger side of the engine that started when the check engine light came on. What could be wrong?

Po171 system too lean bank 1 has come on for the past 2 years. I have had an Indy mechanic and the Dealership look at it and have made many repairs, including MAF sensor, hoses, Oxygen sensor and it is still coming on. The Indy mechanic says he measured it at various times: startup, after a drive, after a long drive and it is only slightly off at startup and not to worry about it. Any suggestions, I would like to sell it and I prefer to fix it first?

I have a 2005 Ford Taurus SE (Flex Fuel), 3.0L, OHV. I recently had my A/C compressor replaced due to a clutch disc failure. The new compressor/clutch works great, engages/disengages properly, and blows COLD air! My problem is that when I come to a stop, wether in gear or in park, my car stalls every time I turn the air conditioner OFF? My check engine light is also on, with a P0174 DTC present (lean condition in bank #2). Any feedback on why the car is stalling would be great, and are the

Bank 2 o2 sensor 1 stays around 420 to 480 stuck in lean comes up with p1054 no activity replaced all 3 plugs on that bank very fuel fowled replaced heated o2 sensor a lot of carbon build up no change bank 1 o2 sensor working correctly switching from lean to rich. even swapped both o2 sensors then bank 2 sensor that was stuck started working perfectly on bank 1. engine runs smooth with new plugs not fouling yet. but will not go into closed loop ever

In-laws towing camper with 1994 Ford Econoline, 220,000 miles on van. While driving on highway, van "shut off." The electrical still worked, but engine would not start. They coasted to side of road, tried to restart, engine would turn over, but not start. My father-in-law looked under hood - said the air filter had "fallen down" and was on top of the engine, but was "disintegrated." Got towed. They were 800 miles from home. Repair shop looked at the van the next morning, and it started.

2001 Ford F150 V6, Truck started spitting and sputtering and check engine light turned on. Originally I thought that I had a fuel problem and maybe needed a tune up so I put new plugs and wires and all new filters, none of these fixed the problem. I hooked up a code scanner and it told me system lean Bank 2. I changed out the O2 sensor and still the same. Could the miss and the system lean code be coming from a faulty injector on bank 2 or could something else be causing this.

OK, here we go. Ford F150 5.4L 3 Valve - 90K miles - so far all work done at Ford Dealer Engine was indicating rich on ECL codes after a spark plug change for a lean. Initially spark plug change yielded a lean condition, changed plug on #3 again - went to a rich condition. All this on bank #1. 20 hours of dealer diagnostics - finally yielded broken roller lifter on #3 intake, replace roller lifer and cam itself on bank one. Now runs nicely at speed, but intermittently engine drops
