Another FNG

Hello From Colorado, I bought this 94 Astro the other day. It has a 5.7L engine tbi its lowered just how much im not sure. it has a few things that need looking at the major one is when you stomp the gas it takes off great but then im guessing around 3500-4000 rpms it acts like it hits a rev limiter. any ideas? anyway seems like a cool forum thx in advanced.

Welcome. Cool looking van.

I'd start by checking the fuel pressure. 9-13psi is required for TBI.

Good Luck.

I was gonna say fuel delivery as well.
Nice looking rig. Youll be happy when she goes eh!
Maybe confirm that V8 injectors are used, not V6 injectors?
You can read a number on the top of each and look it up.

Also, All new ignition cap, rotor wires and plugs can always be a good starting point too..


Oh Ya, and , Welcome !!
