1993 1.3 AAV problems setting ignition timing/rough idle when cold?
Posted: Sun Sep 19, 2021 5:16 pm
Hello all.
I've recently purchased a 93 1.3Spi breadvan. I am currently having issues with poor idle when cold. The ignition timing is currently set to about 15 degrees before TDC. I have tried setting the ignition timing to 5 +/- 1 BTDC as per a Haynes manual. When this is done it will run when Hot but hesitant to Rev. But when engine is cold it will not idle or sometimes start unless I revert back to the original timing.
It has recently had new:
Plugs, dizzy, coil, HT leads, Blue temp sensor, lambda, fuel pump, filters.
I have checked for the correct resistance on all the components on the throttle body and Blue temp sensor and all are within spec. I have checked all wires going to the ECU for breaks.
I have also verified that the engine is timed correctly.
After all of this I can still not set ignition timing correctly.
Any suggestions will be much appreciated
