Did a fuel system cleaning today at work. Hand cleaned all the carbon out of the throttle body (Man was that dirty), did the intake drip into booster line, and finished up with injector cleaner in with the fuel.
Car had a hard time taking all the cleaner in, idled hard and almost died a couple times, thats never happened to me before on any car Ive done it on, but after taking in about half the can and filling the store with a rotten egg smell, my suspicions are confirmed that my cat is pretty clogged. Need to finished off the exhaust and get the header and HFC pipe to eliminate that old cat. But first I need to get a timing belt kit and a winter wheel/tire setup.
Anyway, def. noticed a difference in the car, not a crazy improvement but definitely more eager in acceleration for sure. Need to see if my MPGs improve at all as well.
