Hi and thanks in advance for your help! I recently had a used transmission put in my car and had an o2 sensor wire replaced. When the guy replaced the o2 sensor wire he said he didn't experience any rough idle. I don't have any CEL on. I had a slight rough idle before the o2 sensor wire was replaced but it went away for about 700 miles after the wire was replaced. I had no rough idle whatsoever until yesterday. Now, whenever the car heats up to normal operating temp the car idles very rough and shakes. I just had a tune up (plugs, wires, distributor cap) last summer. Whenever I'm in park or at a stop light it's pretty bad. When I drive at normal speeds, it drives fine. It's really just when I'm stopped. When I put it in reverse this morning it shook worse too. Could it just need new wires?
have the same problem?
