What are the symptoms of bad ignition timing?
What kind of performance/operation would I experience from my engine ('89 L98) if my ignition timing where off (either advanced or retarded)?
Thanks in advance. |

With optimum timing trap speed will be highest, from peak hp.
If timing is too advanced ping and timing retardation will result, as can be seen on a scan tool. If timing is too retarded throttle response will suffer as well as peak hp. |

speaking of timing, what/where is the wire that you have to unplug to get an accurate reading with a timing gun?
it should be 8 degrees on a stock motor, correct? |

If timing is too retarded throttle response will suffer as well as peak hp. And the stock setting is 6*, but the L98 likes it a little advanced so i run 8* |

I thought it was 6. I also had a popping (backfire) from timing being off. Now I have a slight hesitation when hitting the gas, my timing is off a little I did it by ear to get it close. I let someone borrow my timing light and haven't seen it since.

The wire to disconnect is located beside/ behind the dist on the passengers side.One of those weatherproof connectors that looks like an inline fuse holder.Tan with black stripe from memory.
