CEL with p1124 and p1126 with rough idle


Recommended Posts

Hey Folks,

I have a CEL with p1124 and p1126 with irough idle.

I have cleaned MAF and replaced fuel filter.

I have had p1124 in the past couple years(3-4 times), cleaned the MAF and code cleared and does not return for quite 6-12 months.

I have white/grey smoke on startup and above 3k RPMs....this is a new symptom.

Any ideas on next steps?

sounds like the beginning of a failing Air/Oil Separator. you'll want to figure this out quickly, and you may want to stop driving the car until you've figured it out.

the codes are most likely related to a vacuum leak via a torn A/OS bellows tube. replacing the bellows tube by itself requires A/OS removal, so you might as well replace the A/OS since it will fail (or has already begun to fail) eventually. the cost is pretty cheap (~$125 for everything you need) and will take about 3 hours if you DIY. dealer cost is about $400 to replace.

see this post. you can also search this forum for 'separator', you will get a lot of hits.

I had the same 1124 & 26 error codes on my 98 Boxster. All inquires , including tech support from Durametric, gave the following possibilites: vaccum leak, oil cap not on, fuel pump, fuel pressure and MAF. It ended up being as stupid as a sensor loosened up. I reinstalled , cleared the codes and 6 weeks later still no CEL. All those things and more cause the 1124&26 codes. Try the simplest first and work your way up. Good Luck. Ed
