- if it has a distributor, remove the cap and wirebrush the thick white oxide buildup off the 4 electrode points. this affects spark strength especially during cold starts.
- check the spark gap is 1.1mm
- there are two coolant sensors under the distributor. if the ECU sensor reads too cold, it'll cold start too rich and flood. remove the bigger 2-pin ECU coolant sensor and check it's resistance per degreeC in boiling water is within original spec

- remove & clean the idle control valve on the TB. if its stuck closed, it won't allow cold engine to idle fast enough.
