94 gaz/air issue

[rominet]

Hi! i'm from québec so my english is funny and not very very very good. I have trouble while running my 94 sidekick 16 valve 4wd. It look like he dosen't have egnough gaz or air. So wath i have done so far is : changing the fuel filter , rotor and cap , wire and spark plug. I aslo adjust the fire timming with the tork bolt and cleaned the air entry. While doing the cleaning , i noticed a soleinoid with adjustment on it (2 screw) and a big screw before the air intake pallet. About the exaust. I changed the tranny not long ago, by doing this i was able to see the catalyst he was good , not freaking well but good , and the muffler have a good pression at the exit. I was wondering if i need to adjust the air pallet with the soleinoid , or the screw or wathever wath.Or if somebody have the same trouble with the same model and can tell me : look here and here that might be this and this. THX for fast reply : mud is about to frose here and i may want to get my truck a lill dirty soon . THX again !

Okay lil update : I got it ! I have check fire timing , I have adjusted air intake , idle. Fuel filter , also checker compression rate : 180 150 175 180 from rad. then started to remove vaccum while running. And we got it ! it was the vaccum who suck from the intake to the gaz line. Unde the vaccum , there is a big screw , 17 i think , just need to bleed it while running. So for those who experience those probleme BLEED IT FIRST ! after try adjusting evrything.
