Ok I Need Help

[1990GMCSIERRA]

alright when i punch it itl **** sideways and take off spinnin then all of a sudden cut
out for a sec then take off again like a bat outa hell
idk what it could be

new plugs and button,cap is fairley new

 

[71 cuda man]

sounds like fuel,are you running carb or efi?

 

[1990GMCSIERRA]

stock tbi

 

[Mike]

The tbi computer is in no way capable of running a cam and mods without hiccups.

 

[1990GMCSIERRA]

its small,almost stock
it does fine when i kick down on it then al of a sudden spits and cuts out then takes off quick

 

[1990GMCSIERRA]

could it be my fuel pressure regularer or my fuel filter?

 

[1990GMCSIERRA]

ok its not the fuel filter so

 

[noremac]

my guess is the fuel injectors... when you punch it, you are pushin them up to 100% duty cycle.... they may be failing at the extended opening times...

 

[1990GMCSIERRA]

so u think i should clean the injectors?
and why doesnt it do this when i cruising and punch it?

 

[1990GMCSIERRA]

when i rev it up or anything it doesnt do it
