1991 Honda Civic 1.5L Random Engine Failure
My 1991 Honda Civic is having problems with starting and staying on. When I turn the car on it starts but then turns right back off unless I rev the engine with the ignition still in the on position. Also, it used to sit idle at roughly 1500rpms but now its closer to 200-300rpms so low that at times it will want to turn off. Finally, if I put my foot on the gas and bring the engine to about 4000rpms it will stay constant for about 4-5 seconds then dip down to 3000 or lower before it goes back up to 4000. It will do this every 4-5 seconds sometimes dipping as low as 1000rpms and at times even turning the car off altogether. Any thoughts on what it might be?:confused:
