Hey guys i did the m90 swap on my mustang 98 v6.
It was tuned and its being doing great for the past three weeks, three days a go i started it and it felt weird and suddenly a check engine light came up...
So i drove it and it doesnt feel as powerful as it did before, the throttle used to be super super sensitive and as soon as i got n the gas it d rev up so fast without hesitating.
Now it hesitates before reving for an instant, usually when the car s running my vacum/boost gauge reads -18 to -16 vacum i am not sure, now sometimes it has -13 sometimes has -14 or -12 it depends i dont know why, something is not right, i took it to check the codes and it said that
the engine is running lean.
Could it be a bad MAF??
We cleared the codes and now am waiting for them to come again so i can get more details, i have drove it for 160 miles already after i cleared the code and it hasnt come back yet but i know there s some wrong so i ll keep waiting for it to come again.
There are no oil leaks or any kind of fluids on the engine , everything seems clean.
I am also running a front mount IC setup
What can i do??
Do i have to drive it hard to make sure the code comes back or what?? its being 160 miles.
i am driving it slow trying to reach no boost so i dont mess anything up, we are also thinking of taking it to a friend that has a smoke machine maybe that can help me find the leaks or i dont know!~!
please help me guys, thank you.
