I have a 2003 Jetta 2.0l. Started the car the otherday and the car idled very rough, I noticed the check engine light was blinking and kept blinking for about 3 minutes and stayed on (oh by the way the check engine light has been on for about a month need to replace the O2 sensor) As I started to drive the car it was bucking and had no power, hills I drove up in 5th gear I had to down shift to 4th. Also I noticed I am getting interference on the radio, It radio noise doesn't speed up as the car goes faster just a constant sort of thumping static.

When you say you have to replace the oxygen sensor, is that because you pulled the codes and identified the problem? Or is it a guess? IME, the Oxygen sensor is rarely a problem, unless there's another problem that caused damage to it. There are literally HUNDREDS of codes, just for the engine. If the light is flashing, the owner's manual makes it VERY CLEAR that the car is NOT to be driven, as a condition exists which could cause damage to the engine. OBD 2 cars, especially the late ones, can be difficult to diagnose, that's why we access and use the codes to help us more quickly locate and repair the problem.
Advice from people with earlier cars, especially non-OBD 2, is a total waste of time and bandwidth ......the rules, indeed the whole ballgame, are different! For example, there is no distributor, no cap, no rotor, no emissions test port, and no idle control valve. There is, however, and air filter. If you've installed a K&N, it's likely to be a big part of the problem, along with the contaminated MAF sensor that it caused. The check engine light is there because YOU NEED TO CHECK THE ENGINE! Novel concept, huh? Get me ALL the codes, including the COMPLETE text that follows the numbers, and maybe I can help you. The Cap'n |
