  1. Has anyone had their fuel injectors serviced or replaced? Do fuel system additives restore loss injector performance or do they just maintain? What are your thoughts?
  2. I have a Arctic Silver 1997 5 speed Boxster 2.5 all stock with 87,000 miles. Today I damaged the green plastic housing around the tip of one of the fuel injectors. It all started when trying to replace the long oil separator vent line running across the engine. I don't recommend anyone tackle this unless they are prepared to disassemble the entire top of the engine. ;) Question Is it advisable to replace just the damaged injector or should they be replaced in sets? Thanks, Adam STL
  3. Ok everyone here is the scoop. I dropped the car off at Parktown Imports and they found the MAF sensor reading around 2 when it should be reading around 10. I am getting the car back today and will post any new info on these codes if they reappear. Thank you everyone for all your insight and I will continue my adventures as a weekend mechanic. Next on my list a full brake job upgrading rotos and pads. It should be easier than replacing the canvas top which was my first project. Adam
  4. I have driven around 175 miles in town since I changed the fuel filter which improved the engines power. But the idle is still rough at lights causing the car to vibrate a little. When I give it gas it smooths out but comes back when I let off. I haven't reset the CEL 1124 1126 because I made an appointment at Parktown Porsche here in St. Louis (Go Cards!) but now I'm debating on changing the MAF first. Diagnostics I'm told is going to run me $130 / hour until they find the problem. About a year ago the CEL went off so I took it to Greg's Auto which was recommended by a friend but 45 min. drive. They pulled the MAF, cleaned it, and reset the CEL which I respect because they could have just replaced it and charged me for a new one. What about all the injectors being fowled is it possible? What is your feelings on injector cleaners like Lucas? Thanks, Adam
  5. I changed my fuel filter tonight and you wouldn't believe the crap that poured out of it. The stainless steel bowl had dirt and a oil residue. I didn't reset the CEL yet because I wanted to see how it drives before resetting the computer. Over the last week the engine doesn't seem to idle as smooth maybe it's my imagination. The fuel filter instructions in the DIY section are good I just wish someone would explain how to safely raise a Boxster to position jack stands. If I am using a hydraulic jack on the jacking point where do I place the jack stand?
  6. I have a 97 Boxster with the same noise screech at startup about 50% of the time. I finally removed the starter which I outlined in another post and found the bearing on the end of the starter motor was bad. It had a lot of play and the starter motor shaft would vibrate inside the bearing when starting. With the new starter it hasn't happened since. :)
  7. I changed my 97 Boxster starter out a few weeks ago. It is located on top of the engine under the throttle body. First disconnect the negative lead on the battery but make sure you have your radio unlock code ready for when it's reconnected. Remove the throttle body and set aside. Next use a socket rachet to remove the bolts attaching the starter to the engine. The bolt towards the center of the car is easier to access but the bolt towards the passenger side of the car is more of a trick because it's in a tight location. To remove it you need you need a long extension on your rachet to get around several hoses. Make sure you identify how everything is removed while you work to make reassembly easier. :) Oh by the way I changed the starter because 25% of my starts were followed by a hi pitch whine. When I removed the old starter I found the bearings by the gear worn. This week the battery doesn't seem to have enough juice to turn the starter but the battery checked out fine at the shop. Other posts have identified the ignition switch so thats my next project. I have 85,000 miles on the car and drive it everyday.
  8. :( I have a 97 Boxster with 85,000 miles that recently began displaying the CEL for codes 1124 and 1126. I had the codes read at a local parts store to help troubleshoot the issue. The car has no after market parts or modifications and the CEL does not seem to be causing any performance issues. I reset the CEL by disconnecting the battery but it came back after about 25 miles of city driving. My understanding of this issue is that the oxygen sensors before the catalytic converters both sides are detecting an exhaust mixture that is too rich ("Above upper limit / rich mixture threshold"). Since both sides (1-3) and (4-6) are detecting the same issue I am leaning toward an air leak. I would assume if the MAF sensor was bad I would be getting another CEL code. I read the archives here but have seen some conflicting arguments. I bought it over a year ago and have enjoyed learning the ins and outs but this has me stumped. Can someone revisit this issue an point me in the right direction? Thanks, Adam
