Spray carburetor cleaner around the intake if it Smooths out that's the problem

Referring you to hubby, an excellent mechanic. We have Altimas. He will help you. [email protected]

what are the codes that are causing the engine light to come on? need to know that first

Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/sean_54c3a3dc48a7773c

Stop by any good parts store (Autozone, Advance, etc..) and have them do a FREE OBII scan (fault scan) That will show what faults computer has been experiencing. Another question.. When was last "healthy" tune up? Plugs, wires and ALL filters especially FUEL filter? A good tune up usually cures a multitude of stalling and runability issues.

Sounds like rough idle. A full diagnosis of runnability is needed.

sounds like your carb is getting to much air some where check your hoses

look up the codes if they are multiple missfire codes then more than likly you have a bad head gasket

yes the alternator can send dirty ..too high...or too low a voltage to the system causing all sorts of gremlins.. test test

Most likely solution is probably idle sensor.
