changed starter when it went bad...went to start car..tach pegged & car acted like it was 70 degrees of advance (had been running good & starting good)..centrifigual adv, vac advance & vac retard =ok...timing=ok
replaced coil & ignitor..new rotor & dist cap....unplug spark plug wires and
it turns over fine....frustrated!!!!! thank you in advance
This is a 1989 Accord LXI. (292k miles)..code flashing is for Oxygen Sensor

 

Did you check battery condition and state of charge?

 

You state the tach pegged, I can only assume that the true engine rpms matched. Or did the tach peg and just bad idle.

 

checked battery..it is a bit low
tach pegged and went back to zero...idle isnt bad

 

Tach- If memory serves me right, the tach is driven from a blue wire off the coil, you stated it has been replaced but please check. There is an online manual you can download (see DIY section for links).
Engine Perf - If the O2 is bad/setting code, test and replace if bad.
Last suggestion, while down loading and reading the test procedures, put the battery on the charge and make sure it has 12.5v.

 

I'm still thinking it is the distributor..it does start better with a good battery BUT the problem
is still there
