Not about a supra at all, but please help!!!

[87soup]

Before you read this i would like real advice... Not: "get a supra" or "burn it"
:1zhelp: :1zhelp: :1zhelp:
My friend has a 95 chevy truck. V8 5.7l anyways...

The damn thing drives soo rough!!! The motor sounds strong, but it will go every once and a while, almost like the transmission is slipping... Then it will die at idle or low RPM... When the lights are on it also dies...

Thank you!!!

My friend had the same problem on his chevy truck(same year as your friends with the same engine). He found out that his fuel pump was bad plus we replaced the negative cable on the battery because it was very bad. Did your friend ever replace his fuel pump on his chevy truck?

Check the alternator and battery, those will often cause problems with stalling when the lights are on.

Then check the usual - plugs, wires, does it use a distributor? If so then cap, rotor...

Thank you Guy's... He has new plugs wires, and cap... But the alternator is questionable... So is the fuel pump!!!

I'm leaning towards the alternator, cause the lights wouldn't have anything to do with the fuel filter or fuel pump. Good luck either way.

It might not sound like a fuel pump but on my friends truck it did the same thing as 87soup has listed. His truck would die when you go into drive(or any other gear than park), it would idle for about 2 mins then die unless you gave it gas but also I would agree on testing the alternator to see if it is good or not.

Sounds like the fuel mixture is to low.

 

[87soup]

The fuel mixture could also be jacked up...

not supra related = OT.

as for an answer to your question. look at the plugs. anything look wrong on any one of them? as stated: cap, rotor, wires, plugs. check your timing, too.

You try changing the idle mixture servo? unplug the four prong plug on the TB and see if it runs better....if so...its bad
