    Cylinder fouling AGAIN

    I don't think I've ever mentioned this before, as it's always been pretty easy to diagnose the problem....but it's getting repetitive. I drove my 2003 P5 across town yesterday morning until about noon without any problem at all. My daughter came over to visit, and we needed to run to the store...

    Dumb question. How far is too far when "restoring" a P5?

    Let's face it.... I love my car, and it's paid for. But there's some things that need fixing (mostly cosmetic) such as a few spots of rust I've noticed, and huge dents in difficult to fix places (previous owner was a mountain biker, had a roof rack, and well.....the rest you could guess I'm...

    Downstream O2 sensor replacement

    I've been having a P0037 code going off for a few weeks, and finally got the cash to spare to buy the new downstream sensor - a Bosch direct replacement, not a universal. Anything I should need a heads up on before I attempt replacing this thing myself? Any tips and tricks to share would be...

    Obd2 scanner?

    Does anyone know of an obd2 scanner and app that works with the iPhone and protege5? I've currently got a CEL on, but once that's sorted, I'd like to have something to monitor other things...fuel mileage, for starters. Sent from my iPhone using Tapatalk

    blacked out headlights on a silver mp5?

    First question: Has anyone done this and have pics to share? I'm thinking about giving it a try and want a preview first. Second question: I'd like to replace my stock fog lamps (one is busted and needs replacing anyway) and would like to try something aftermarket, but in the same size. Is...

    CAI - weight savings??

    I just installed an Injen cold air intake. I figure with all the parts I took off, fasteners no longer needed, and room left in the engine compartment, there must be some weight savings. Has anyone actually calculated it? From bone stock, what's the general consensus for MPG and HP differences?

    best pics for CAI??

    I recently found a hole in my stock intake tube. I did a temporary fix with duct tape, which seems to be holding well enough that I'm going to hold off on replacing it with a cold air intake system instead. Now, since I don't want any cheap crap, what's the best choice for the best fitting and...

    sick baby :(

    A few weeks ago, my P5's engine light came on, and has been running horribly since. It's a manual transmission, and getting started has become really tough. I try to take off, and I can feel the engine shake and it seems like it's going to stall. I push the clutch in, and either give more gas or...

    aftermarket car stereo picks (not pics)

    What's your favorite for a double-DIN Bluetooth installed car stereo? I bought a JVC XR-810 back in February, an I've had nothing but trouble with it. It's now going back for its FOURTH warranty repair, for which I have had to pay the shipping to the repair center, and then my time and fuel...

    Low MPG?

    Since I've had my '03 P5, I've replaced the coil packs and plugs, air filter, I run sea-foam with almost every tank of gas, and most recently, I had a fuel system service done at a shop. I was told that I could expect a great increase in economy after the fuel system service, but I'm not...

    Losing MPG, slight power loss

    I bought my Protege5 this year, picked it up on the Friday before Easter with 97,500 miles on it. I've always noticed an intermittent "miss" when at highway speeds and while accelerating. One day I was out playing on a twisty road, got on it a little harder than usual, and then the power...
