CEL went off over the weekend, Durametric showed a P2190 code.
Car is a 2007 C4S coupe w/ Tip at 69,000 miles. Basically bone stock, serviced at the dealer.
After checking with Durametric I opened the hood and noticed that the hose clamp connecting the wide Y hose from the airbox onto the intake manifold came loose. So I though there is a vacuum leak, took off the airbox, replaced the airfilter, cleaned the MAF. noticed a few ml of oil-like fluid inside the throttle body just at the level of the butterfly flap; so I cleaned that up. Tightened oil fill and gas caps. Reconnected everything, cleared the code but now it came back a day later. I have an appointment with the dealer in a few days.
Any suggestions what I can do to maybe fix this on my own? Many thanks
I have 2000 Porsche Boxster S that is misfiring on nearly every cylinder. It started with symptoms of a bad MAF; typical sluggish on take off, CEL light with the corresponding code. I would disconnect the wiring from the MAF and it would clear up. I cleaned the MAF and plenum and it ran perfectly for about a day. Ordered a new MAF. By before I had a chance to put the new one in I got a flashing CEL and a massive loss of power. Put in the new MAF. It cleared up some idle issues but the loss of power and flashing CEL is still there. The codes show random misfire and misfire on 2,3,4,5, and 6. I've also changed the spark plugs but it has had no effect.
Hello. Great site. I recently purchased a 04 996 AE with 113K. My OBD showed random misfires. I checked the plugs and coils. Coils were cracked so I replaced all plugs and coils. The plug condition was consistent across all cylinders... ash gray color and no pitting or carbon or oily plugs. The misfire codes returned and I noticed the idle is rough but the engine pulls and is smooth off idle and through the rev range. I purchase the Durametric and I ran actual values (codes showed random misfires across most cylinders) the check engine light came on at one point but had gone away on it's one while waiting for my cable to arrive.
My problem is I have lots of data to look at but no way to understand or to translate it into actionable information. I am not even sure that I captured the right parameters for my misfire error codes. Is there a good place to look at what the actual values should be for a 996? or a link to any tutorials on how to read the data and translate that into a what to check or troubleshoot?
Any advice would be greatly appreciated and thoroughly utilized.
I took it to the shop and the car shows those system too lean in bank 1 and bank 2, do i have to replace anything?
The mechanic told me we should replace the coils in #4 and #5 because they are misfiring due to something.
Any ideas before i go buying new coils?
Hi there folks,
I’m having some random misfires in my ’03 Boxster. I’ve disassembled the intake manifold to get a better understanding of the problem, and as per the picture below, there is clearly something going on with cylinder-1.
a week ago, CEL came on for random misfires in cylinder-1 (P0301) Engine runs well, has high millage (320km) and no noticeable degradation in performance Checked the coolant, and was below the minimum mark (which was flushed a couple of months ago) On the exhaust side, there are dripping marks, probably coolant leaking through the exhaust manifold gasket (!) All this makes me think that it’s leaking coolant through the head gasket into cylinder-1. I already know this is not a four-hour repair to be completed during a weekend, and that one way or another, the engine will have to come down for surgery. . so I'll definitively appreciate any inputs!
