when climbing a hill the car bucks and pops thru the carb, from a start it hesitates, also smells like gas
car bucks and pops thru the carb on 2002 Subaru Outback
I'd say, check out the ignition system. The popping back through the throttle body (no carb - fuel injected) makes me suspect ignition. Check the wires for proper resistance, should be about 5k ohms/foot. check the coil for about 13 ohms from coil tower to the opposing tower. If it's very low, it may be a shorted coil. Look for arcing, too. Find out where the fuel smell is coming from, if it's the exhaust, it's because of a bad miss. If it's leaking somewhere, you need t fix that ASAP.
Thank You. Shortly after receiving your thoughts I pulled the plugs, they were cooked. I changed the coil, wires and plugs,, it's been running like a top. The gas leak was a loose clamp, which I found in the process.
