So I fixed the coolant temp sensor wires, and calibrated the TPS, it runs like a dream. Drove it for about 130 miles Now on the way home form work the CEL came back on. Its 25 and 26 which is nuts at the same time and also 34 which I'm assuming is because of the other 2 codes. I looked and it has some places to start...fuel injectors, coolant temp sensor afm...but since I've never seen either one of those codes in this car I was wondering if maybe what I did affected one of these components and has set off these new codes. Any ideas guys? thanks...

Anyone? Do I need to give more information. I'm just so surprised how 3 codes I have never seen pop up literally 130 miles after I fix 2 or 3 others. My dad always said that if you replace one hose, the pressure from that one is bound to break another and so on and so forth...This kind of reminds me of the same situation. lol

Any chance this is a California spec car? When 25/26 come on at the same time it means either the OX sensor signal is switching too fast, or the cylinder to cylinder rpm variation is too large, a crude misfire detection. This capability was only in the CA spec ECU though. Do you have any "gadgets" interfering with the OX sensor signal?

You can check the OX sensor here
