FLASHING SERVICE ENGINE SOON LIGHT!
I've got a 2000 SSEI that I changed the spark plugs in about 2 months ago. That was a little trickier than I thought. I ended up REreplacing the plugs after 2 were bad. It ran like crap so I changed the plug wires. I took it out and gave it hell, ran ok. Now, when I go to get on it, either from a stop or on the highway, it kind of lunges (not really a miss, but might be). What is the symptom of a faulty O2 sensor? Could I have messed that up when I was struggling to get to the back spark plug?? My gaps and everything is ok with the wires. I know a flashing service engine soon light is not good, but it turns off after about 10 seconds. Any suggestions???
