Your "not starting" can't possibly be related to your Torque app not connecting to the your PCM unless your PCM is toast. This is about as rare as a polar bear in Phoenix, so let's start ruling things out. Try any of the other number of free apps to use your bluetooth connector, or use a...

Why did you need to rev it to 5k rpms to get it in first? When you are stopped, the transmission and engine will meet at 0 rpms. Anything higher will require the clutch to slip. The white smoke is a bad sign though. Tweety is probably right, sounds like you blew the head gasket and you have...

Bearings don't typically squeak, they usually make a grinding metal on metal sound when they go. You sure it isn't just a belt? Sounds like you've got some wrench time under your belt, so you get the benefit of the doubt, but all the bearings I've replaced haven't solved a single "squeak".

Endlinks are not a great design, because the bolt is at a 90 degree from the stress it is bearing. The nut has to be tight enough to keep the bolt from shifting back and forth within the holes on the sway bar and the strut, and they aren't really designed for that. Find nuts with the largest...

I had a tiny pin hole exhaust leak on my MSP once where the support bracket was welded to my muffler. I noticed because I could smell it and there is noway I would live with that for more than a day or two. I also have driven a C6 with cats removed. Within a minute or two I was nauseous and...

22 AFR is pretty much open air. That means you have misfired. Many people think that a misfire means you have a bunch of unburnt fuel and you will be terribly rich (<12 AFR). What they don't understand is that an O2 sensor only measures oxygen. If fuel is unburnt then it passes right by the...

Any improvement?

Did you reset the PCM? All you need to do is pull the negative wire off the battery and either turn on the lights or step on the brake pedal to kill any charge in the system. You had +25 LTFT's and now your car doesn't have a vacuum leak (or at least the main one was fixed), so your car is...

Sounds like you have a fuel problem not spark. Throw a data logging wide band on there like an LC1 and record a few runs. I'll bet you'll be very surprised. I don't think he has an accurate boost gauge that is telling him when he is at full boost. 4200 happens to be exactly where the MSP PCM...

Thanks for posting those. I am going to take a closer look at mine.

Thanks for the info guys. got_psi, looks like the links to the pictures aren't working.

got_psi. Can you see the cracks visibly? I'd really appreciate a picture. Also, how many miles, what boost/tune have you been running and for how long? Also, have you tightened your bolts past spec?

I really don't have any proof that the weight is a major factor, but Callaway put that bracket there for a reason. Even if a poll clearly indicated the majority of cracked manifolds had aftermarket DP's, it could just be that most people with aftermarket DP's also run higher boost or piggybacks...

Can you take a picture of the crack? I'd like to see the exact shape and size as well as the location.

Cast iron can certainly handle the heat, it actually expands much less than stainless steel. Nearly every stock manifold (exotics not included) I've ever seen regardless of aspiration is cast iron. The manifolds on the Corvette ZR1 are cast iron. GT500 also cast. Mits EVO. All produce much...

I have a real hard time believing anything like this on Ebay will fit without modification and last more than a month. But, if I was in need of a manifold, I would be seriously tempted to give it a try. If you go for it, certainly let everyone know how it works out. The stock one is going to...

Yeah that's how it goes. I got that one quickly, but I've spent a whole day on the rear motor mount with multiple trips to the hardware store, so don't feel bad. 3 hours is nothing in the long run. How's the car running now?

I haven't found my car to be that sensitive to the gap. I just have the cheap autozone counter gap tool and they've all been close enough out of the package, right around .30 gap. How do you know they were misfiring at 30? .28 vs .30 shouldn't make a huge difference; I don't even have a .28...

Every 6 months or so I have to retighten my manifold bolts. The first time it happened I had no idea what it was either, sounded like a diesel VW bug until it warmed up. I posted a bunch of vids etc. Eventually someone PM'd me and told me to check those bolts. When I took off the heat...

If you have a leak, it has built up a lot of carbon where the leak was, so you'll want to clean that with some brake clean. The cleaner the surfaces are the better, but the metal gasket is there to make the seal. What makes you so sure it is the gasket? Are all your bolts tight? Can you see...
