I recently bought a cable setup to connect Tunerpro RT to my ’95 K1500 w/350 TBI and I’ve noticed that I’m getting knocks on the counter at about 50% throttle and above. It’s 5 speed with 178,000 on the clock and it’s almost never at 50%+ throttle but it still bothers me and I’d like to try to figure out what is causing it. Is there a normal amount of knock under load on a warm engine with that many miles?
I’m thinking maybe it’s carbon deposits, perhaps in the intake and or on the pistons. What’s the best way to clean that? Is there a product that will clean the intake effectively without removing it? I had it off a few years ago to replace the gasket but I didn’t see any carbon to speak of. I also replaced the EGR a couple years ago.
What about the TBI, what is there to clean/service on it besides the injectors? I plan to send them to witchhunter to be cleaned soon.
It hasn’t been all that many miles since I replaced the plugs, plug wires, distributor rotor, and distributor cap. I just replaced the O2 sensor, temp sensor, PCV valve and fuel filter last week. I also verified the timing, with a light, is at 0 TDC with the advance wire disconnected. I plan to verify it with a piston stop as soon as I get a chance.
Any other suggestions?
