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?

tx

fuel filter

sounds like the compressor kicking in and out. turn off the air or defroster and see if it still continues.

it's not the air conditioner.. as i turned off and the problem persists..... Can anybody tell me where is the fuel filter so i can take at look at it?

Should be tucked inside the left frame rail midway between the front and back or approximately in line with the drivers door.
