Okay, when i accelerate, the revvs start to stumble around 4 grand and doesn't go past. It does this in every gear. Has anyone experienced this and possibly know how to fix the problem? Greatly appreciated.

 

check vaccum leaks and the MAF and also you could be runing rich

 

How can I test the MAFS?

 

Hey, clean the MAFS out with some safe carb and choke cleaner. I dont think any of the non-MAFS-safe stuff will hurt one using it once, but it is better to be safe than sorry.
I hadnt heard from you so I thought you had that thing all straightened out.
They can be tricky little birds sometimes, but stick it out and dont get too frustrated. You need to learn somehow right?

 

Yup, sprayed some carb cleaner in there a few times and she revvs happily past 7.
