    Code 172 just won't go away...arrrggghh

    I don't hear an exhaust leak as best I can tell. And I don't see any black soot of any kind at the manifold flange....although I certainly have black on the inside of my tailpipes and they are only 30 days old. The CEL does not come on for a while. I may drive 20 mins and after the car has...

    Code 172 just won't go away...arrrggghh

    I installed a BBK offroad Hpipe after removing the factory cat mid pipe. I will go back under there today loosen and reset the manifold to H pipe flange and see if that helps. Thanks.

    Code 172 just won't go away...arrrggghh

    I put in new Hpipe (removed cats) and exhaust and got a CEL. Ran codes and among other codes was 172 - too lean bank 1. CEL is intermittent. Comes on here and there for about 10 seconds, then goes away. Figured time for a tuneup anyway so I replaced: Plugs, cap, rotor, coil, ECT, MAF...

    Oreillys gave me wrong O2 sensors...aaarrggghhh

    Went to pick up replacement O2's this morning at Oreilys. The replacement O2's looked like the wrong ones as well. Looking online, it turns out the replacement and the wrong one from yesterday are "downstream". the box is labeled correctly but wrong ones....aaarrrggghhh

    Oreillys gave me wrong O2 sensors...aaarrggghhh

    I installed two new Bosch O2 sensors from Oreillys. As I was installing the second one, I noticed it looked different than the first. I looked at the box and the numbers matched, so I thought little of it. After installing, I then drove about 30 miles, in stop and go traffic....ummm...and I...

    Low RPM/idle engine/trans wobble?

    Engine/trans wobble/vibration at idle. If I tap the accelerator above 1000 it goes away, only to return when the RPM's settle back about 700 or 800. This all started a few weeks ago and shortly after I got an intermittent CEL. Upon acceleration the wobble goes away, but if I cruise at 1500...

    Manifold stud nut size?

    i know when they came off....err snapped off, the socket was a 15mm, i think... the 1/2 inch nut i tried seemed too loose although with the taper on the stud it does tighten but the 12mm .175 fits more like the original. i am thinking if it is too tight i may blow it up. tough to tell cause of...

    Manifold stud nut size?

    I have new manifold to midpipe studs from Ford part N808447-S100 btw. They did not have the nuts. Found nuts at Home Depot. The thread on the stud is tapered so it locks on, thus I can only thread the nut about 3/8 inch or so before it locks on. Not sure whether the nut is m12-1.75 or...

    AmericanMuscle.com issue

    I ordered online a Pypes exhaust combo which came with a Pypes xpipe. As soon as I hit enter to complete the purchase I read a few Reviews and several peeps did not like the Pypes xpipe. So, within a few minutes of entering my order I called AmericanMuscle. He asked me a few questions about...

    Xpipe and Pypes catback - my experience

    Install - BBX x pipe and Pypes Violator catback...rather lengthy, but I have to vent...LOL...plus a few tips. Teardown - removing factory catpipe but keeping factory manifold. I did not replace the factory manifold with headers at this time, afraid of breaking studs off in the block. 1)...

    X Pipe at WOT is too much

    I installed BBK xpipe and Pypes Violator cat back. It sounds badass at low throttle and revving at no load. On the street at WOT going through the gears I think I break the sound barrier with a screaming high pitched sound. At 3000 rpm plus or so, under load, it sounds like the Tin Man being...

    Noisy Speedometer tach recalibrate?

    It is not sound from the speakers. With the radio off, it still makes a buzzing sound coming from the speedometer cluster. It comes and goes and is louder depending on my speed.

    Noisy Speedometer tach recalibrate?

    Speedo/tach makes a buzzing noise when accelerating....comes and goes and it is loud like gears turning...quiets down at cruising speed, so maybe it is the tach. I took the speedo apart and oiled the odometer gears, (only gears I could see) but that was no help. Now I put everything back...

    steering wheel vibration while braking

    Installed EBC rotors and Red Stuff Pads....they work great and look awesome. Now I have a vibration in my steering wheel while braking. There is zero pulse or vibration in the brake pedal, so I don't suspect warped rotors. My struts are pretty old, tie rods, etc. Any help is...

    New clutch whines

    I am not angry at the mechanic, I perfectly understand......angry at myself for getting myself into this issue. I will take my car back to him and have him supply the bearings and get it fixed.
