Question about Chevrolet S 10

My 1995 Chevy S10 sparks knock really bad.I have added some octane booster, but it still knocks badly.How can I adjust the ignition timing? I swaped the engine from a 2000 S10.I used the head off of the 1995 engine.Could changing the head make it spark knock? The truck runs good at idle.I am puzzled at this point!

Did you upgrade or change your computer? ECM has a plate, I am a loss for the name, but that is programed to your old motor. You might check into that I can't think of anything else would cause that. Darrell S

Changed out the knock sensor and engine light is still on


Some engine lights don't turn off until the car is driven for awhile. Give it some time. If it doesn't go away, take it to Auto zone to clear the engine code. If it comes back, then it might be a wire problem and not the knock sensor itself. Good luck!

What is the cause of detonation noise ?


Wrong spark plugs?
Make sure you use iridium plugs by NGK or Denso.
NGK V-Power Plugs BKR5E-11

Carbon Buildup?
Get some Techron and run several tanks

Wrong Octane?
Your engine should use regular gas. But you might be getting some low grade gas. You can try using a higher octane fuel. Or try adding a octane booster.

Spark knock-


Is the check engine light on ?
The computer should be able to adjust ignition timing to stop the pinging if it really is spark knock. Its possible you have an ignition timing problem, or low fuel pressure.

Timing should be set by the PCM. So you cant adjust the timing. However if you have a faulty knock sensor the PCM cant tell the proper time to fire. The knock sensor picks up on ignition ping and adjust the time to send spark to the plugs.. Other causes of ping can be the engine temp, faulty EGR or the engine can be to lean.

I got po324 code on my 2005 chevy aveo what does this means


knock control system error.

That system adjusts the spark timing so that the engine will not knock (precombustion) if it is under heavy loads, such as going uphill, or when using lower octane fuels.
Yes, a timing belt slippage could cause this problem as the crankshaft and cam are no longer in sync. Could also be a bad knock sensor or broken wire.

What part of the engine knocks when your knock sensor is bad on a 11995 cutlass supreme sl


Hello: The Knock Sensors purpose is to detect pre-ignition, when the computer receives a knock signal it re tarts the timing to prevent the pre-ignition. Any mechanical related knock will activate the knock sensor signal. If the knock sensor is bad it WILL NOT cause the engine to knock.......

1999 accord ex knocking really bad.Should I replace the spark plugs and put in a higher octan gas


No, the condition of the spark plugs will not provoke a knock. Also, do not put higher octane gas than recommended for you accord. Higher octane will not cure a really bad knocking condition, just a mild one under hard acceleration. In all probability, the knock sensor is malfunctioning, or the computer is getting erroneous readings from the timing sensor. Both possibilities can be determined with a computer scan.

Developing a ping... not bad gas, low miles


It may not be bad gas, but it could be the wrong octane rating for that engine. Check your owner's manual and see what octane is recommended for that engine. If you're running 87 octane and it requires 91 or higher octane, then you need to be running the higher octane fuel. By running lower octane fuel in an engine that requires higher octane, your getting pre-ignition, the knocking sound you hear. What's happening is that as the piston moves up on the compression stroke, the gas/air mixture is compressing and as the pressure goes up, so does the temperature of that mixture. It's possible that temperature can get so hot that the gas/air mixture ignites from the high temperature and not from the spark plug. Higher octane fuel will help this since higher octane fuel is harder to ignite. I say try running some 92 or higher octane fuel in your car and see if you still hear the knocking.

Hello there:
on these types of lights what is needed to be done is after the repairs are made the vehicle needs to be taken to a Kragen or a Autozone so they can hook up the FREE DIAGNOSTIC CENTER AND CLEAR THE CODE
otherewise this will continue to appear till it is cleared from the cars computer memory ok
Hope this is very helpful

Spark knocks when taking off from idling/starts to miss after sitting at idle


The 2 most common causes of spark knock are #1 ignition timing too high, and #2 Low octane fuel. Check your ignition timing, and try a mid grade 89 octane or 91 octane fuel, or you could use an octane booster in your fuel. Good Luck! I hope you find this to be very helpful!
