Hey friends.... I do have a 2000 blazer V6.
I got this problem when idle with a gear on. The RPM stays fine but aprox every other 2 minutes they go down, as the engine will turn off, but just 2 senconds later it goes again to normal levels.
It's a issue like having a bad spark plug, but i check them loke a month ago and they were fine and as the problem happens every 2 minutes i imagine it could be something else.
Addiitional, when driving a high climb you cant feel like the engine has not enough power like and you can feell the RPM problem highier.
the car has 50 M Kms.
any guess? what should i check?
