Odd starting problem

[coolskaterkid]

93 Legacy 2.2 auto

 

First thing in the morning around 30 degrees or so, it will start right up no problem, but the last two days trying to leave work, it just cranks and cranks. So the first day i pumped the pedal and it fired ran rough, was missing, and i looked out the rearview, and tons of bluish smoke. It cleared up after 5 miles or so, then today same issue. All i can think of is oil is fouling the plugs, but why would gassing it get it to fire?

 

Also not sure if this is related, but at idle the car shakes, almost like its dropping a cylinder, or a miss, i listened to the exhaust and it pops a little. But the least bit of gas and everything clears up.

Clogged PCV valve?

How many miles does the car have? I had a similar problem with my high mileage 2.2 I think it may have been coolant temp sensor related but never really figured it out.

 

Sounds like basic tuneup time if this hasnt been done for a while:

new air filter

new pcv valve

new fuel filter,

plugs (ngk)

wires (ngk or subaru oem)

 

This stuff should be less than $100 total, and if nothing else may help power/mileage

Well the air filters only a couple weeks old the plugs NGk have 10k on them, not sure how old the wires are will try that fuel filter is 3 months old I cleaned the PVC 6 months ago will replace that too. It's got 210k on it now

Yep, I'd go for a decent tuneup, plugs, PCV valve, leads, all filters, fluids, etc. See if that works. If not, I'd be looking towards the CTS for the hard starting issue, as they can make the computer think it's warm when its not if malfunctioning and not deliver enough fuel to start it.
