True, It's a cheap start though going with the PCV valve along with O2 sensor..Most are reasonably cheap...However that MAF is another story. Hopefully it's just a faulty PCV or O2 sensor.
Yep, but If I'm fairly good with this stuff, and with help from a bunch of people I can reach the same ting for cheaper, and learning something in the process and then I can help other people with the same problem.
This sounds just like a case of a well use vehicle. How many miles on it? Doesnt matter. Matter you got a tank of badish gas. Invest in a can of seafoam. Fill up, use the can of seafoam, run that tank to the light and then fill up again. Calculate that tank and see where it gets you.
