I'd appreciate any comments, as I'm trying to fix this myself. I have basic knowledge about the Motronic from the Probst book,experience, and other sources. I really don't want to cut into the Kevlar helmet fund to take it to the shop. My current helmet is a Snell M85 Marushin overdue enough for replacement that the padding is disintegrating. I've tried to replace it a few times in the past and just haven't found one that fits as well as the Marushin. Shaking bits of padding out of my hair is telling me how stupid I've been. So I really need to wrak braintrusts to fix this so I don't wind up wrakking MY brain literally. I will try to put the pertinent stuff first. Way high HC(559ppm) @ idle, idle CO: 0.63% California Limits at idle for my car are HC:120ppm and CO 1.0% My readings at 2500 RPM are HC:35ppm and CO 0.47% California limits at 2500 RPM are HC:140ppm and CO 1.0% Exhaust CO2 at idle is 13.0%. O2 is 2.3 (measured idle of 669, although it goes back and forth between 600-800) Exhaust CO2 at 2500(actually 2407rpm) is 14.4%. O2 is 0.5% Watching the meter, the tech told me the HC numbers jump at the same time as the idle transition. I neglected to ask him if it jumps on the way up or down. He was convinced that the problem was the Mass Air Sensor(even after I pointed out twice that this car has an Air Flow Meter instead) so I didn't bother asking too many questions. I've had a low or loping idle for as long as I've owned this car(almost 4 years). This is the first time it hasn't passed the biennial inspection. Previously, I've passed with numbers low enough to qualify as a Ultra Low Emissions vehicle! That was probably due to several vacuum leaks leaning out the mixture. Those have all been fixed including the injector o-rings. Car has 156,000 miles, mine for last 65,000. Engine related mods are a Dinan chip and a Metric Mechanic System 300 exhaust. The exhaust is comprised of the 50mm Euro downpipes, a 2 into 1 Catalytic converter, and a Bosal muffler. Recently got new spark plugs(old ones all look good and alike-new ones gapped wide), cap&rotor, and valve adjustment (.014 stone cold) as well as cleaning and reoiling the drop-in K&N air filter Parts replaced over past few years(some more than once) include: Ignition wires, all intake rubber with the exception of the charcoal canister hoses, oil filler gasket, idle control valve, Main relay, cold start injector, injector o-rings. Items checked: All injectors are clicking(all original), all electrical connections are have been cleaned or checked, including plug wires. Fuel pressure checks ok per Bentley. Temp sensor & thermo time switch in range. Air flow meter tests ok although resistance track is worn-most severely at idle position. Reference Sensor and Speed sensor removed,cleaned and swapped with no change. Replaced a few vacuum hoses again and verified no leaks as much as I could by spraying carb cleaner at all joints. Dipstick seals well. O2 sensor is a year and a half old and is putting out ~230-~900mv. Tried running open loop for a few days with no change. Battery voltage and connections good. Oh, by the way, the car runs spectacularly at all engine rpms but idle. Pulls well and no misfires. Idles fairly strongly now with just a hint of a miss at the same time the rpm occillates. What's next? Air Flow Meter? Ignition Coil? leaking fuel injector? or maybe a few clogged ones throwing off the computer and flooding the other ones? even though all the spark plugs look normal?

What? You didn't see any M5s at Daytona? Me neither. or LMRs or BMW factory support of any kind. I don't know how modified those Vipers were(I'm assuming A LOT) but you don't win a 24 hour race with dumb luck. Let alone finish 1-2. I'm still lusting after a M5 as I always have, and will probably buy one variation or another used in the next few years. But after watching last weeks race, I can't help looking at Vipers in a different light and considering owning one, something I never had an interest in before last week. Any one from BMW corporate out there? I've owned all German cars with the exception of one Toyota & one Datsun and I'm considering an American car based on their performance at Daytona. I have NEVER considered owning an American car before. BMW not having a strong corporate presence at "The premier Road Racing endurance event in the US" is unthinkable and a sad indicator of the direction of this carmaker. This event showcases the two strengths BMW is historically known for: exceptional handling & quality engineering. What happened to the LMRs? I know there was a class shift but????

That would be from the end of the Rolex 24 Sunday to the moment I saw what one of my mates just picked up. Tuesday night at the local watering hole he produced the latest fruit of being a private auto importer/exporter: a Genuine Ferrari Dino GT with just 12,000 miles on its 2.4l V6. Already having had a few beers I declined asking to take it for a spin. Good thing as I then found out it still had the stock nearly 30 year old tires on it. Sure it's not a "real" Ferrari since it doesn't have a V-12 and it isn't red but it's close enough for me, especially since it's a bit more affordable. Maybe I'll stop by his house and borrow it for a few hours this weekend. It sure sounded good. So the Viper is long forgotten. I'd still settle for an M5 but I wonder what old Countachs are going for these days?

It does not matter if you are listing to radio or to cassette, antenna will be up. It should go down if you turn radio off regardless of whether the ignition is on or off. Someone could have messed up the wiring in the trunk if the antenna goes up whenever the ignition is on. I believe there is a 'hot when radio on' and a 'hot when ignition on' and even a 'hot at all times' in the wiring. Someone might have switched a couple. chris pawlowicz '89 325i '74 2002 ------------------------------ Date: Fri, 11 Feb 2000 04:27:07 -0800 (PST) From: Matthew Yip <[EMAIL PROTECTED]> Subject: Re: [uuc] <WOB> My Viper lust is over OK - I'll be picky - it was never called a Ferrari although that was the manufacturing company. The "proper" name for the car is a Dino 246. A local racer/associate has a Countach. After seeing the trials and tribulations that he goes through, I think I'll stick with the M5. I've know the guy for several years and his Lambo has been needing a clutch for the entire time. Apparently the clutch assy is balanced ON THE CAR. The estimate is $12K - I haven't spent that much in UPGRADES on the M5 in 4 years!! - --- Erick Baumeister <[EMAIL PROTECTED]> wrote: > a Genuine Ferrari Dino GT with just 12,000 miles on its 2.4l V6. > So the Viper is long forgotten.

Something is causing a misfire at idle. It seems that your ignition is good. What does the O2 sensor do at idle? That will tell you if you are too rich or too lean. Actually, if you are misfiring badly at idle, the sensor will see O2 and try to richen the mixture, but with low CO, the mixture cannot be too rich. Try a cylinder balance test (disconnect one plug at a time) to see if one cylinder is doing all the missing. Your injectors may be clogged up causing poor delivery at short pulse widths.

Wear your seat belt and keep your airbag. If you have an SUV, be advised that they roll over in 33% of accidents compared to 8% for cars. NEVER ride/drive an SUV without a seatbelt. It is one of the most dangerous things you can do. Rollover and no seat belt means big hurt. Gary Derian <[EMAIL PROTECTED]> > Windbags, er airbags aren't all they're cracked up to be.

The most important thing was to ask the dealer about the clutch wear while the tranny was out of the car...oh well, hopefully your clutch was ok, as hopefully they would've called to say it needed to be replaced.
