SOURCE: 2001 buick regal w/ bad ignition coil and clogged catylitic conv.

Hello! The defective ignition coil more than likely contaminated the downstream O2 sensor...If there isn't a trouble code and engine performs in a normal fashion, there's no reason to change the upstream sensor...

93 Buick roadmaster, replaced speed sensor already, car still did same thing


Erratic Speedometer action could be an internal transmission problem. Check the Instrument cluster, vehicle speed buffer and recheck the speed sensor, look at the drive gear inside.

I have 2 catalytic converters on my 1996 Buick Roadmaster, I know 1 of them is bad. How can I tell which 1 it is so that I can buy the right one?


If one is bad you replace both
You have a 1996 bad or not their
over 14 years old so they get replaced
at that point,as they no longer are efficient
enough to process oxygen
You use the PO420 & PO430 codes you should
have as well as look at scan tool data,fuel trim,& back
probe & test the O2 Sensors.
If you hit them by hand when cold they may rattle
as the material inside is broken prosibly
Average person can not tell much,so no
Need experience & proper test equipment
Just replace both side & the front O2 sensors yourself

My 1993 Buick Roadmaster hesitates and jumps going up hills.


Have the fuel pressure checked the fuel pressure regulator valve may be acting up, it should be at 30 psi or greater at idle. It may also be a Oxygen sensor causing the car to run lean on acceleration, if it has never been changed have the primary or bank 1 O2 sensor changed out they should be done every 60,000 - 80,000 miles. If all this has been done there may be a vacuum leak somewher in the system and by the way all vacuum hoses should have been checked during the tune up.

96 Buick Roadmaster running lean.


That is an oxygen sensor, these sensors send a signal to the computor to adjust the rich/lean fuel mixture.
When a code comes up for them, they generally need replacing.
