check your maf sensor, it controls your fuel/air mixture, or Idle air control valve when its warm can you smell gas at all? If you can take off your intake and clean it with MAF cleaner.

i got her in the shop and found 60 psi (dry/ with oil) in one then 120 on 2-3-4 and 150 with oil in 2-3-4. it has milk oil (bad head gasket i belive) and im guessing its blown on one. i pulled the whole motor and put it on a stand. some one was in this motor recently im sure of it it has a brand new clutch with assembly greas and red greas on the bearing in the crank. (its late and been a long night and i cant think) they used silicone on EVERYTHING, intake, EXHAUST!!, timing cover, oil pan ect so i figure ill do a rear main oil pan timing cover and chain while i do the head gasket. i have a feeling the last person did the head and may have used silicone on the head gasket! well ill keep posted and take some pics of inside the motor!!

I had the same exact problem. Previous owner said the fuel pump was new. Well I tried everything and it all came back to the fuel pump. I yanked it out and seen that his mech lied to him the fuel pump was old. I swapped it out and runs perfect.

Seen the rest yikes that sucks

Put a new / used motor in it cause it had a bad HG. Doesn't do it now.... weird the motor I put in has a bad noise so I'm bummed on that. Gave the thing to my dad and he's in love. Lol I still gotta get him a motor
