my saturns acting up. low rpm acceleration, miss, stumbles, bogs

[sayhuh?]

Thank you for all of the info sayhuh? It's supposed to warm up a couple days this week so I'm going to have to get my dmm out and start checking these circuits. It's irritating that both codes tell me the same list of crap that could be wrong. I know my vacuum hoses are good since I just replaced them when I changed the motor. I didnt get the code 26 till I hit the.deer a few weeks ago. I think the purge canister is up there somewhere

I had a problem with my TDi going into Limp Mode. Similar to yours but in a diesel. I replaced all vacuum lines, the actuator and even some of the relays and got nothing, so I know your pain. One other thing to consider, and may sound odd, is the cat. If it gets clogged it will cause too much back pressure problems as well. Too much back pressure might cause the backfire through the intake as the exhaust has no where to go. I could be wrong, but being an older car, it may be this.

I never fixed mine completely lol, but still averaged 48-50mpg, so I quit trying. Spent too much money on a car with 350k miles on it.

If it's a clogged cat I've heard after you drive it for a bit that bish should be glowing red and you said it's cold so you should see where the exhaust comes out when you start it up.

ok so one of my spark plug wires slipped up off of the coil pack.. i think the miss is gone, it ran good last night, but still have the ses light after 30 seconds... i also would like to note that my cruise control doesnt work... i assume it runs off of the vacuum system
