Car acting up.... i'm puzzled!
so i've been driving my car for a couple of years now without a glitch. On my way home today the car started to act funny, the rpm'* starting rise and drop and the more gas i gave it the more it bogged down until it completely stalled. i fired it up after about 30 seconds and it ran fine until couple of miles down the road when it started to act up again so i shut it off, waited for a minute and off i went again. I repeated this over and over until i eventually made it home. i thought it my be a plugged fuel filter but that wasn't it, checked all the vacuum lines and they were all fine. The only other thing that i could come up with is the cat. When i shake it, it sounds like the core is in a million pieces but then why does it run fine for the first few minutes if the exhaust is obstructed??? i had lots of gas, all fluids are full and it didn't overheat blah, blah, blah... any help is appreciated, thanks in advance.
