Check engine light after installing cat converter and 02 sensor

Hi,
I have a 1998 VW Beetle 2.0 and my check engine light came on and started blinking. My car started driving real ruff and hesitating. According to the manual it said that I had a problem with my cat converter. I went ahead and had my friend install a new cat converter, new o2 sensors and I had him do a tune-up. Now my problem is that the check engine light came back on after one day of me using my car. The car has been drive excellent, now I don't know what the problem could be. Does anyone have any idea what else I should check?

Manual can not tell you the problem relaited to check engine light . I mean point the problem . You have to use scaner to retreive the code from ECU and go from there. You could save a lot of money by retreiving code from ECU in the first place , instead of doing guesswork.

2003 impala. Hard starts and fumes smell.


this is what i found for you

The catalytic converter has an oxygen sensor in front and behind it. When the vehicle is warm and running in closed loop mode, the upstream oxygen sensorwaveform reading should fluctuate. The downstream O2 sensoricon1.png reading should be fairly steady. Typically the P0420 code triggers the Check Engine Light if the readings of the two sensors are similar. This is indicative of (among other things) a converter that is not working as efficiently as it should be (according to specs). It is part of the vehicle emissions system.

Most likely, the aftermarket cat they installed is a high flow cat. This commonly causes issues with throwing that code on our cars. You can either have an OE cat installed, or just have the code deleted from the PCM by someone that has a tuner.
Good Luck

Check Engine Light see codes below


P0171 is LEAN and P0303 is misfire number 3 cyl. Its time to stop guessing and pay for a correct diagnosis. Find a shop that works on VW and has the tools to work on it. DO NOT put those Bosch Platinum Spark plugs in that Ottozone tries to sell everybody.

Need to know the codes before we can do anything else.
I'll have to get back to you on the voltage at O2 sensors but they could be ok. Cat's perfect output gotta be 100 degrees lower than input. Get codes and I'll help you out.
Try our manuals section to get spec's.

Check engine light came on recently. Car then


The exhaust system has two 02 sensors One before the cat converter and one after. The #2 02 behind the cat converter is the one that trips the light if emmisions are unacceptable coming out of the converter. The #1 or front 02 sensor monitors and constantly adjusts the fuel to stay within parameters. If the #2 tries to compensate for an inefficient converter and it conflicts with the #1 02, the ebgine will run poorly due to either too rich or too lean fuel adjustment. Have the #2 02 sensor replaced and the converter checked. Good luck
