So I decided instead of doing a back pressure this time I would buy a cheaper inspection camera from harbor freight and take a look inside my cats to visually diagnose my bank 1 cat is bad. This worked out great and I had great results. Definitely recommend the cheap AMES inspection camera for...

I was driving this morning and my car was driving as usual, I didn't feel anything different. It still runs rough and acceleration is rough and sluggish, but I figured I have a vacuum leak somewhere that I haven't found with a smoke test (going to redo a smoke test soon). But I decide to check...

Was going through maintenance on my 05 325 I got back in December. Fixed P0171+P0174, replaced the PCV valve plus the hoses, valve cover gasket, intake manifold gasket, all 6 plugs and a coil. Cars been fine for a week, until the CEL popped back on. Pulled the codes and it’s just P0174 by its...

Little bit of a backstory but put short, I hit a curb my oil pan cracked, i got a “heater sprayer not working” code and i called it a day. I got my oil pan replaced as well as the gasket and i changed my oil filter and gave a coolant flush while i was at it. haven’t touched my transmission...

Hi all, I have a custom built E46 M3, we are facing an issue which we could not solve yet, and we are running out of ideas. The problem started with a hesitation during acceleration, it is more noticeable in higher gears, e.g.: pull in 5th gear, but I can feel it in 3rd gear, and even in 2nd...

Hi everyone, I just replaced my motor mounts and used an engine support bar to lift it up a couple inches. I drove a bit after the install and got an SES, just a p0174 code. Any first thoughts as to what I may have pulled/stretched/cracked/etc. by lifting up the engine? Intake boot on top looks...

Replaced the thermostat and the water pump recently, and changed out the coolant (which if it helps any, my car did not take alot of new coolant only about a gallon, despite me draining it as best I could, but the car isn't over heating and the temp gage stays steady in the middle, maybe an air...

A little while back I had a lean code (P0174) throw and I posted on here about it. I ended building a cheap smoke tester and tried that out. I couldn't see any visible smoke, even after multiple different tries. (Yes I removed the oil fill cap and let the crankcase be filled with smoke, the put...

I have been trying to diagnose and remedy this problem for several months, and now I need the to call on the collective knowledge of the group. It all began when SES illuminated one morning as I was on my way to dealer for routine maintenance. The car was behaving normally on the roughly one...

Hey everybody, I recently picked up a 2004 325i and I'm looking for some advice with the infamous P0171 and P0174 lean codes. I've tried a few super easy and cheap things that I figured would be a good place to start before spending large amounts of money on parts. Some background on the car: it...

Hey guys, I searched the forums already and saw some issues similar to mine but nothing 100% similar. About 4 days ago, I got a P0102 code. I decided to grab some MAF cleaner and hit my MAF up a little bit and clear my code too see if that fixed it. So no biggie there. Following this, about a...

Hi. I have a 2000 bmw 320i with 213k kilometers. It has the M54B22 engnine. My car threw P0171 and P0174 along with codes for camshaft position sensor.

Long time lurker, first time poster. Sorry for the long post, but I can't seem to eliminate the lean codes and misfires at low RPMs. I'm a mechanic, but generally work on classic cars from the '60s through '90s, though I'm no stranger to modern cars. This, however, is my first BMW...

PROBLEM A I won't be able to start the car up until I get a replacement starter. Before that exploded on me, I was getting the following codes. The car would also shake at idle and low-rpm power was awful. Here's what my Autel MD-802 gave me. Codes were in this order: P1347: Misfire cylinder...
