Ok. car is manual 2000 1.8t with 114K miles.

Just had $100 dollars of work for check engine light code done.

Bill for the work says: "check had code 17545 P1137, Long term trim fuel, bank 1 system too rich. checked and found vacume hose3 to fuel pressure regulator and to throttle body broken. Replaced both hoses, braided hoses"

What else do you guys think could be f*cked up here? (o2 sensor after cat was just replaced a couple of weekes ago)- something like MAF lines? this is bugging the **** outta me. Any advice/help WILL help me sleep better tonight.

 

Well has the CEL come back since they fixed it? That sounds reasonable.

 

Yes, it has. That's the point, Im about to take it back, but I would like to have some possible ideas in my head of what it can be, before I randomly get charged again. So like what are so more troubled ares with this code?

 

I guess I would suspect the MAF then, although the MAF usually causes lean conditions.

 

Alright thanks, I'm taking it to shop in 30 min, I'll tell ya how it went.

 

stumped, good luck

 

OK, came back from shop.
They checked all problem areas for that code. Everything came up fine (after $150 of their time). Decided to change the MAF sensor anyways. Guy said it could have been intermittent fault. So far so good, but ya never know.
