That engine has 2 knock sensors in it and they are UNDERNEITH the intake manifold. You MUST remove the intake to service them. NO OTHER WAY.
The sensor is located under the intake manifold. It takes about 2 and half hours to replace the intake manifold, book time. Knock sensor is about $35 + $60-$90/hr labor. So you are talking about $300.
225 60 16
Low to mid-5s
60 to 66 psi.
The 4.3L engine in 2002 should have 60 to 66 psi of fuel pressure.
It's 60
My guess would be wheel balance.
I have a 2002 demo model, and its 60 watts per channel. peak power not rms.
4.3L engine, 60 to 66 psi. 2.2L engine, 41 to 47 psi.
knock, knock...whos there? bathtub...bathtub who? i dont know.
Once the knock sensor is set on the computer tells the fuel injectors to only go to about 60 percent. Or half depending on who you talk to. Check cables and connections first. If these are OK then get another sensor from a wrecking yard and connect it without removing the old one. Then tie it down tight to the intake manifold. Run the engine again and see if the issue goes away. Then decide if you are going to get in the engine and replace the sensor.
Yes. It will be a bit wider and shorter than your stock 205/75-15 tire.
