Can’t diagnose CEL & Coolant Temp Light

[TheNoblePoptart]

I’ve got a CEL for the following:

P1124 P1126 with P0130 P0150 P0115 marked as pending in my OBD II Reader

On top of that I have the quick blink for the engine temp sensor on my water temp gauge.

Really I am perplexed, coolant is topped off and no visible sign of any leaks and car runs as expected. I got the car for a steal a few days ago and went in expecting a few thousand in repair. Other issues are the wipers not working and the air con not blowing cold air.

If I clear the CEL it stays off for atleast a day, tends to come back on if I idle for a while.

Any people smarter than me who can weigh in? I’ve tried to research it on here and some other forums but everybody seems to have slightly different codes. I’m planning to change out the spark plugs and coils and clean the MAF this week is it worth throwing in the two pre car O2 sensors or should I just assume the worst and prepare for a costly exhaust overhaul?

Thank you!
