Probably a stupid question, but here it goes:
93 'trac, essentially bone stock with 155k miles. Newer plugs, wires, cap (18 months ago), new cat (2 weeks ago), all major services done/updated/taken care of by and large. Great car...runs really, really well.
Except for the last few weeks - whether the engine is cold or hot, engine feels like it bogs down significantly/loses power UNTIL the turbo spools and then it responds great - like always. I've done the usual checks and tests (per all the discussion I've seen and searched through in other posts in the forums) but I am stumped.
Could it be the 02 sensor? They've probably seen better days. Maybe the EGR valve? Of late, she smells like she's running a little rich.
Open to thoughts or things I should investigate and try - hopefully it's nothing major. This think has gotten a significant overhaul this year - can't afford much more!
