so a little back story i bought this 95 tacoma 3.4l v6 truck and it drove somewhat fine it just wouldnt go over 55 so i checked the spark plugs and found not a lot but a good bit of oil and the spark plugs and someone had put the tube gaskets in backwards. So i changed valve cover and tube gaskets along with new spark plugs and coil packs. I took picture before i took it apart and when i put back together and went to crank it turned over and then it dies. I made sure i plug and put everything back together right and it looks just how i took it apart. Hose are all back on the right spot and coil pack harness is right. i got fuel pressure. i got spark. i clean the MAF sensor and the throttle body. But when i spray brake cleaner on the throttle body and it was like i was spraying starter fluid and would fire up higher rpms and then die again. Ive been mess with for a few days a done a ton of research and tried a bunch of tips and trick and still wont stay running. Some people say it a vacuum leak but i replaced a few hose already. So maybe you have a thought on what it could be?
Well that is a classic sign of a vacuum leg. There are so many places you can get vacuum lakes. It would make your head spin. I personally use a smoke machine inject smoking until the intake system and see where the smoke comes out or pay a mechanic who has such a machine to check it
