I have a 90 chev blazer that runs rough when i apply the brake ,it also has a high idle and runs rich .?


I would look at the vacuum booster control unit .
This is the power assiest for the brakes it runs off the main engine vacuum,
If its leaking inturnailly you would lose engine vacuum that would make it run rough when you hit the brakes .
Also if the check valve inside of this unit were stuck it could cause a vary high idle
Try hitting the brake pedel when its idleing high in park and see what effict it has on the engine speed .
If it changes this is for sure your problem.

I have a Kia Rio 2005 Cinco( 5 door) Running really rough until I push down gas pedal,,, Then it seems lOk still a little r bogged down', It doesn't stall just runs rough without accelerration? Oxyg


To begin with, is your "check engine (CE)" light on? If it was on and now its not, you need to replace the bulb. If CE lights is on, find out the codes before doing anything. If bulb is good and "CE" does not come on, begin with: (1) gapping spark plugs, (2) replace spark plug wires (if haven't changed them within the last 2), then the coil. If your Cinco is still idles rough, adjust gas pedal until idling smoothly. If this still doesn't help, replace your two oxygen sensors. If still running rough, the converter. After doing all this and problem is still present, take it to a mechanic you trust.

1996 Chev Cavalier chugging and stalling running rough idle


Bad injectors causing the vehicle to run poorly can cause other damages to sensors etc. Buy a code reader and check the codes.
