I've done a ton of work over the last year getting my car clear of CEL's and running well again. I replaced the IMRC, MAF, and finally a new computer. The car has been running well for a few months now, but a few weeks ago I got the infamous P1518, secondaries stuck open, again. I tweaked on the cable a bit, and had AZ clear the code for me. It was good for a few weeks, but it did it again the other day. Once again I tweaked the cable a bit and had the code cleared. That lasted 4-days. I'm getting REALLY tired of this BS.
I thought I remembered reading that I could possibly clean the secondary valves. Is this what I should be looking at? Other suggestions? She's running great besides this. I may be selling her in the next few months (I've got an opportunity for a killer deal on a Maxima SE), and I would like to get this cleared up so the next owner doesn't have to pull their hair out dealing with this stupid code. Thanks!
