1998 buick riviera blinking check engine soon light

The check engine light is on and occassionally will blink. The car seems to be running fine. Had a bad feeling about gas I put in the car a few months ago - thought it may have been bad or even accidentally diesel because light came on right after that

That most likely is exactly correct. When that light flashes means damage is being done! You will find the catalyst converter is the victim. Only when flashing is this occurring. Should shut down asap when this happens

Has the fuel filter been chg. lately. If it has, maybe a fuel pressure test is in order. Fuel pump might be geeting weak and does not show up until it gets warmed up. Fuel pumps are a common problem on this type of cars.

It NEVER was the camshaft sensor! Unless, you've removed the engine lately, which I doubt.
RUN to Advance Auto Parts and buy a can of "SeaFoam" and add to your gas tank per instructions...drive at least 100 miles and the problem should go away...IF it doesn't you'll have to replace the O2 sensors in the exhaust system...Any good mechanic should be able to do this for much less $$ than the dealership DO NOT go to the dealer for repairs!
Good Luck

Make sure that you have the ventilation tubing when replacing the battery. The car is designed to vent battery gases from beneath the car. Substituting a different type battery (without vent ports, a small hole that is located at each end of the battery ) or if you decide to use the battery without the ventilation tubing, you run the risk of an explosion. This is due to the proximity of the battery to the fuel pump, which is also located beneath the seat.Underhood batteries vent naturally into the air within the engine compartment. In your car there is a small hole in front of your battery that leads to the underside of your car.Your tubing is designed to carry the battery's vapors way and direct it out of your car through this hole.

gear position indicator will start blinking a code(?) You may think it's blinking a code , but it's not . Doesn't have the capability to do that . Traction, security light on - take it and have DTC'S - diagnostic trouble codes checked . Sounds like you have insturment cluster problem , Without testing anything that would be a guess . Take it to a qualifieed repair shop an have it diagnosed .

Can I get codes without scanner 96 buick riviera


A 96 is OBDII, you can not pull codes with out a code reader. Up until roughly 94 on some models it was possible to jump 2 pins on the diagnostic port. The check engine light would then blink the codes. You can buy a relatively inexpensive code reader or about $50. Let me know if you have any questions and I'll do my best to answer them. Thank you for using FixYa.com!

More than likely, you have a failed fan clutch. That is a frequent problem on the 4.3 I6 engine. It will cause a roaring noise and "vibration" and allow the engine to overheat at low road speeds. As far as your check engine light and other driveablity problems, it may or may not be associated. Have someone with a code reader check it. The TrailBlazers were infamous for electrical gremlins.
