2.3L ('83-'97) Smoke Testing 2.3L Lima

[R3tr0grade]

Hello, I've been battling a lean code on my truck since I bought it. Replacing the MAF and O2 sensors seemed to help last year (the code stayed off for about 8 months) but now its back with a vengeance. When I smoke test, I don't get much of anything except some smoke from the IAC vent which I assume is normal, and some smoke from the EGR (is this normal?)

I've already replaced the pcv and some vacuum hoses connected to the EVAP system. Also I had the heater control valve fail on me and the vacuum on that was shot but I just capped it. I also don't think that would cause an engine vacuum leak?

Thoughts? Thanks!

I moved the thread to the four cylinder engines section for better visibility and continuity.

Since this is a duplicate, I'll clos this one down so all the information is in the same thread. Two separate threads will create confusion.
