My 1987 Fiero GT (stock V6 automatic) bogs down and dies when the gas pedal is pushed after being stopped for a few seconds, like at a stop sign. We've cleaned out the throttle body and replaced the spark plugs and throttle position sensor. Any ideas of where to go next? Thank you!

I'd start with basics... such as fuel pressure.

After everything I went through working on the 86 gt to figure out why it had the same issue I wish I had started with simply checking fuel pressure.

Harbor freight sells two fuel pressure checker kits, the cheaper of the two is all you need and it's only $20ish.

Deleting the pulsator was the only thing my car technically needed to fix it.

Thank you for the replies! Looking more into the pulsator issue, that sounds like what I'm running into. It looks like the pulsator connects to the fuel pump output and fuel feed line. I'm curious as to anyone who has bypassed this - is the pulsator actually inside the tank, or right outside? How easy is it to bypass in your garage with basic tool? Is it doable without dropping the fuel tank?

The pulsator is often replaced with a short piece of submersible hose (not regular fuel line). The tank needs to be dropped.

First things first.. test the fuel pressure.
