P1131 when driving car hard
Hello I have a 1999 svt contour 2.5 litre. I bought it last month for a really low price because it was throwing 5 or 6 check engine light codes and the dealer didn't want to handle it.
Ayhow, the main issue is vacum leaks and the intake manifold linkage, the imrc. I took apart the intake manifold , bought a new plastic clip, fixed the linkage, changed the gaskets and the egr gaskets. It fixed everything except p1131 shows when I drive the car hard when its warm. I keep looking and finding split hoses here and there but I need to get this handled fast. The car has flunked emissions control testing for over a year because no one has fixed the car before me. I have to buy temporary permits every time I drive it to the testing station. Every time I think I have fixed it , it throws p1131 and I have to try and fix it and then I have to reset the computer and start again. It takes a long time to get the catalyst and evap monitors reset - I haven''t succeeded yet. Any other advice to get this handled besides looking for more vacum leaks? I might try cleaning the Mass air flow.
