Cdavis95Z71
Newbie
Sorry I know this there’s tons of threads on this but I just want to fix my truck and I need some help. I have a 95 Sierra z71 that runs super rough and I don’t daily drive it anymore but I love the truck and I can’t let it sit around the corner collecting dust anymore. Previous owner never did any maintenance so I’ve been playing catch up with that for 3 years of owning it. But down to the problem. It runs really rough. Stutters and almost stalls when I give it gas and has no power until I get above 3k rpm. I’ve replaced the ignition coil, egr valve distributor cap and rotor, wires plugs and I replaced the cylinder heads a while ago and it ran great for about a year after that. It has good compression and what not and I made sure I timed it properly. It honestly feels like it has a few vacuum leaks. My plan right now is to replace all vacuum lines and rebuilt the tbi but there’s so much going on in that engine bay that I’m not sure what else to replace or what might be the problem. I’m going to check the fuel pressure as well to see if that might be a problem. What do you guys think or suggest. I apologize for such a long post, any help is much appreciated.
