Rough idling, how do I fix my particular issue?

Blinking check engine light? Don't drive with it blinking. Have your codes read. May cause severe damage to engine if driving it with a blinking cel. What are the cel codes?

P0131-HO2S Circuit Low Voltage Bank 1 Sensor 1 P0171-Fuel Trim System Lean Bank 1 P0300-Engine Misfire Detected C0055-Rear Wheel Speed Sensor Circuit Malfunction C0035-Left Front Wheel Speed Sensor Circuit Malfunction Those are the codes that I got off the truck this evening.

Sorry been out of town. Have you tried cleaning your maf sensor? How close are you till your next plug change? Also these codes tend to make me think that your 02 sensor on drivers side closet to manifold might be bad.

I am not sure which 02 sensor was bad but my truck has 200,000+ on it and the 02 sensors are original, so I just replaced them all and my check engine light is off and it is idling perfect no more issues. Sorry it took me so long to get back to you I just replaced the sensors last night. Thank you for your input it was very helpful now I have my truck running like normal.

Glad to help

where do I find the MAF on a 2007 Silverado?

The MAF filter should be located between air filter box and hose to engine air intake. You should see it between a couple of hose clamps just outside your air filter box. Be careful on removal of electronic connectors not to force and break. Best advice is to do a Youtube search on how to clean your MAF. It's not difficult at all and only takes minutes. I've done it several times.

I have a 98 chevy Silverado changed spark plugs and wires on it a friend had scanner and scanned it and it still misfires I'm no expert but could my manifold be dirty and that's why it misfires? I need help

I have a 03. It's a throttle body sensor. Issue that's right at the breather and the intake. I had the exact same thing happen to me. But of course I don't trust many people being a woman. I done alot until I found out what it was. Hope you have alot of luck. It's Not Hard. I done it myself.
