SOURCE: high idle and misfire cylinder 1

This could have several causes however the most likely cause is either a throttle positioning sensor or the mass air flow sensor is bad. To check either of them you need to have an OBDII scanner that can read voltage. It would be best to send it to your local GM tech to have them do an onboard diagnostic rather than spend alot on parts that may not solve the problem.

SOURCE: Cylinder #2 Misfire-after intake manifold replaced

It's possible he has two plug wires crossed, or pulled a spak plug wire apart replace #2 spark plug wire First. To test check the firing order and make sure all the wires on the right plugs and the correct place on the distributor, if it is right, then buy a can of carburator cleaner and spray around the intake gasket if the engine revs up when you spray the carb cleaner around the intake manifold with (engine running) if the engine rpm revs up you have an intake leak.

I have a 2001 Chevy s10 that I put an aftermarket air intake on. With high acceleration speeds, the car would lunge and stall. The engine would also quit. You need to make sure that you have no leaks in your intake manifold. If you have leaks in your manifold, your vehical will misfire. Check your air intake manifold by turning on your vehical on and running your hands up and down the air intake. If you feel air coming out, you have a leak. This needs to be corrected. I hope this helps! Please rate 4 thumbs up!

Spray around the intake manifold with carb cleaner. If the engine smooths out or revs up, fix the leak. It sounds like a leaking intake manifold gasket.

I have ran into this problem. When the car is cold the vehicle will run good. When it warms up the vehicle might start acting up. Spray carb cleaner on the back of the intake air manifold Doesthe car bog or rev up.The manifolds expand as they warm up and create an intake gasket vacum leak. Some mechanics don't know how to use the scanner. Did they go into the misfire moniter on scanner? What are the fuel trims, this will tell if the vehicle is running rich or running lean. This is a hard problem to diagnose if you don't know how to read a scanner. If you could tell me the fuel trim readings I could help you out more. You can have a misfire and not have a check engine light on. But I am willing to bet the intake manifold is leaking.

Intermittent Misfire on cyl #4 1997 Buick Lesabre


How's your coolant level? The intake manifolds on the 3.8L engines are prone to breakage at various locations causing coolant leaks into the crankcase and vacuum leaks on intake ports.Removal of the upper intake manifold will be necessary for inspection. Also, check for vacuum leaks at various locations on the outside of the intake manifold using WD-40 or brakeclean/carburetor cleaner sprayed hoses, non-electrical components, at the base of the manifold etc. As for a faulty injector, not likely but if you suspect one you can always swap the suspect injector with another on the engine and see if the misfire follows the injector. Just be sure to relieve the fuel pressure before servicing. Hope this helps.

LOUD TICKING NOISE IN ENGINE AFTER INTAKE REPAIR


How long have you ran the engine ? I know that they will run rough and sometimes make strange noises for a few secounds or a little bit untill everything get oiled up again. I would make sure all the push rods are back in the right place and that all the lifters are tight.
