Replacing intake gasket

I have a 2001 chevy 2500 suburban with a 6.0L engine. I have a miss while idleing and when increaing speed and the check engine light is flashing. I changed the plugs and wire within the past 6 months so I checked that no wires were loose and used fuel injection cleaner but still have the miss. Took it to a local dealership and the mechanic said he was 99.9% sure I needed my intake gasket replaced. He said it was bad on the #5 plug. They want 550.00 -600.00 to replace the gasket. How difficult is it to replace the gasket myself and where can I find info on doing this?

You could have what is called a lean misfire which is caused by an intake manifold leak. Only you know if you are skilled enough to change the gasket yourself. Call the dealership and ask them what the book labor time is for the job, that time is for a skilled Tech. with all the proper tools. That will give you an indication of what you are up against.

Why does my 2001 Chevy suburban 6.0L idle rough at startup with AC on?


when the A/C is on there is a solenoid that speeds up the engine for the required load of the compressor. You probably have a bad solenoid or miss adjusted solenoid

When my 2002 Chevy Suburban is first started, it idles rough and starts missing (cold idle). The "check engine light" is now on.


spray carb/choke cleaner around intake gasket mating surface to heads if it changes rpm of motor you have a bad intake gasket. my 03 did this 2 wks ago. they have a plastic gasket set for $39.00 (felpro) or you can purchase the steel felpro set for $80.00. If your keeping truck buy the steel as they are heavy duty and highly recommended. Maybe get a code scan and see what it has to say; ( lean, misfire on 1 or 2 bank )

My 2001 chevy suburban when it is cold and you start it the idle will go to about two grand then will start running rough and die what could cause this issue?


Generally a high idle like that is caused by a vacuum leak. Start checking your vacuum lines and your intake manifold for holes, cracks, or tears. If you can't see any, then get a can of ether, and with the engine running, spray all around where the intake meets the engine block, and all around your vacuum hoses under the hood. If the idle suddenly dips or rises, you have found your leak. Most of the time, it is just a cracked rubber line, or an intake gasket. If there is no leak found, your Idle Air Control valve may be sticking, that is normally located on the side of the intake where the throttle plate is located. Remove the 2 bolts holding it in and see if the valve and chamber are full of carbon. IACs are pretty cheap parts to replace. Let me know what you find and i'll try to hlpe you further. Good Luck

I have a 2001 dodge ram 2500 with a V-10. It has started running rough at low speed and ideling at stop lights. It does not stall just runs rough. It was just tuned up in June 2010. There are no warning...


Did you replace the Fuel filter? Have you checked for Leaky Vacuum hoses or bad Intake gasket.
The easiest way to tell if it is a bad vacuum leak is to spray Carb cleaner while the car is running at idle around the intake gasket and throttle body . You will find the leak once you spray a spot and it idles better.
Please leave me a good feedback on here.

You might consider replacing the cam sensor. The computer relys on this signal in order to generate spark timing.

99 suberban missing at idle after warm


Code shows missfire on No 1 cylider. When engine is cold it runs a rich mixture. If the missfire is still No 1 then check for vac leak on manifold. Perhaps a vac line or intake gasket.
