420A 420a idle relearn?

[Redrum_8247]

I have a 98 Eclipse RS that I had recently just bought and done a timing kit on. Runs n drives great. No check engine light or such.

When driving though, it tends to drop idle/stall more often when it has a load, lights, radio, etc. I've tried to research and find things but it's all mainly for the 4g's and "universal" terms.

I would start with testing the alternator.

Alternator tests fine. Did a tune up and fuel cleaner. Plug three was drier than the Sahara though. Starting to think it's an injector now. But it is only when it warms up, runs fine cold

It probably runs fine while cold because it runs richer. Once it warms up and closed loop that cylinder gets starved of fuel. RockAuto had some fuel injectors for $20 a few years back so I'd probably check and replace that injector and see what happens. But that's assuming there is no place near you to clean and flow test your OEM injectors.

I'll have to tear into it and take it into work. Hoping it's just a clogged injector. More issues than I bargained for though for sure. Was just supposed to be a timing deal n done
