95 G20 Van Runs Like Crap When Hot

[SpiderGearsMan]

My friend has a 95 G20 van w/350. He tells me it fires up & runs OK when it's cold, but once it's warmed up it falls on it's face & stalls when you hit the gas & you have to floor board the gas pedal to get it to restart. He changed plugs, wires, ignition module, put a 'known good' throttle body & new gasket on it & it still does the same thing.

Ideas? Spidey you there???

start with a fuel filter
check fuel pressure . look for tbi fuel pressure regulator ..9=12 psi ..check for leaks and of course ..CHECK THE COIL tower for chalky residue corrosion ..coils go a lot
pickup coil in distributor

Yay, closure, cheap closure.

Sorta, but not before he added a fuel pump, tune-up, chopped the cat off...

[TheSilverBuick]

Doh!

I knew this too. Dammit, as many problems as that causes with fuel regulation I swear its gonna be the first thing I change every time.

Like I said... seen it many times and its a cheap fix(unless you
throw all sorts of parts at it until you change the temp sensor...
oh well... glad you got it

I'm glad he got it too, it was a learning experience for both of us..
