    99 cobra hesitates after 4k rpms

    Questions: What brand of O2 sensors are on the vehicle right now? You mentioned the exhaust temps pre and post cat being 50 deg different. This could be due to a fuel mixture and depending on what brand of sensors you have, it could eventually lead to clogged cats. Does the vehicle have a tune...

    99 cobra hesitates after 4k rpms

    I recall someone unplugging the sensor and wrapping it up with foam padding of some sort and leaving it in the valley. There was no mention of any CEL codes. If anyone needs a referral to a tuner who knows how to turn the KS off, let me know and I will post his link/info.

    99 cobra hesitates after 4k rpms

    At the lip. Correct! The Mach 1 alt pulley is larger than the 96-98 and 99-01 cobra. Also, the Mach alt uses a "clutch" type pulley, while ours are a slide in and bolt up. I know it's not much, but I was offering a 3.2" (lip) and 2.95" (ribs) pulley to help alleviate the possible over-spinning...

    99 cobra hesitates after 4k rpms

    That's about right. 2.48" is what they measure at. Not sure what else your issue could be, but if you can't solve it with all the other fixes, I might recommend seeing if someone local with a 99-01 can swap their alt with you and see if the problem disappears. Can you datalog?

    99 cobra hesitates after 4k rpms

    Did you measure? If your alternator pulley is smaller than stock, it overspins at higher RPMs and voltage begins to cut out. This causes the vehicle to hesitate at higher RPMs. My question was a serious one.

    99 cobra hesitates after 4k rpms

    You mentioned a new alternator. Did you reuse your stock/factory alternator pulley or are you using the one that came with the replacement? Check the diameter of the alt pulley and measure it from lip to lip and give us your measurements. Also, do you have aftermarket accessory pulleys?

    98 cobra cuts out and bogs at wot?? Bad fuel pump? What fuel psi at wot?

    It's most probably a voltage problem. Check your alternator pulley. If it's smaller than your original one, the alternator is over spining and causing the voltage to cut out at higher rpms. Also, if the alternator is not suited for your vehicle, you may experience this as well. Your stock...

    Let's play good COP, bad COP...

    Misfire? Hesitation?.. Check for this and chances are, some of your COPs might have a crack in them. Mine had 4 of these damn things cracked. Probably a good idea to replace them every 20-30K miles..or when necessary. Without spring = cracked to shit (OEM that came with my motor)...

    Why I recommend FELPRO gaskets and seals
