I'm having a hard time figuring out why my car is having a small problem being sluggish while turning over, idling heavy(as far as vibration goes, rpm is a little under 1000), and the exhaust is puffing louder than normal. I had an oil change saturday, drove for 4 hours sunday and when i was almost to where i was going i started losing power and thats when the shaking started. i check the dipstick and it was below the first dot, so i put oil in. The oil never leaked out on the 4 hour drive back home. today i replaced the spark plugs and wires and pulled the negative cable off to clear any timing adjustments, but still the same things going on. any ideas as to what's happening?
Thanks, Ricky
