Regular unleaded is fine. If you are experiencing pinging or knocking your car needs to be looked at by a mechanic.

82 Octane. Higher Octanes are for higher compression vehicles, too high and you will get bad mileage as it is harder to burn

Likely your brake light switch has gone bad and the battery has been run down by the lights being on. the switch is above the pedal. Change the switch and re-charge your battery.

ODB code for Chevy Beretta


low voltage at electronic spark timing circuit, or functional test failure

First thing to do is to test the knock system. If the ECM isn't seeing knock from the system then it will error on code 43. If you have a scan tool it makes it much easier to do this. You can then just look for knock counts.

On a warm engine, bring the idle up to about 1000 RPM, and rap on the passenger side of the block. The engine RPM should drop a little then come back up, and the scan tool reported knock counts should increase.

If not, then the knock system is faulty.

If the above test is OK, listen for knock the next time you take it WOT. If you can't hear any then the knock system isn't going to report it either. It may be from too high an octane fuel, too low of timing, or just a detonation resistent engine.

My 1989 chevy beretta will not go in gears i have fluid it was going in drive but now it locked in a gear and would not go.


I actually have the same issue with my '90 Beretta. I have not yet had the time to look at it but I could suggest that either your master or slave clutch cylinder is shot or your clutch linkage needs to be tuned/replaced. A Master clutch will run about $50.00 at your Autozone or Advanced Auto, and the slave is about $40.00. I'm not sure wht the linkage will run you, nor do I know the cost of repair if you decide to have a mechanic fix it for you.
