So, I've had this problem for about 3 weeks now. I drive 1/2 mile to the highway both to and from work.....and then 20+ miles on the highway at around 65 mph. The problem seems to start on the highway and lasts for about 5-8 miles of my commute and then it goes away. I found out this weekend that it happens irregardless of operating temperature though. If I shut the vehicle off and turn it back on.....even with it still warm.....the problem starts over again.
Bascially it feels like someone turned the key off for second while I'm driving down the road....and then turned it right back on. The weird thing is that it consistently happens in 10 second intervals. I can count 1...2....3....and then at 10 seconds the vehicle stalls a little and the rpm drops.....then after 1 second of this it comes right back to full power....and it continues like this for quite a few miles. The check engine light hasn't come on yet....I'm not sure if there are any codes in the system though.
I've been reading other posts as much as possible and the things I have replaced because of them are: plugs, wires, cap, and rotor. I also checked the fuel pressure and it seems to remain consistent. I bought a new CPS, but I haven't swapped it out yet because it seems that those are either bad or they aren't.....not usually in between??
My thoughts are either the CPS or an O2 sensor, but I really don't know.
Any help would be appreciated.
