hi all , i have a camaro 350 tpi i have a new engine , distributor with module, coil wire and spark plugg .. i have a ignition box too and a 58 mm bbk trottle body, i have no leak of vaccum and my timming is set to 6*... the idle still not running good... all of my injectors have 16.1 ohms and i test it with a 12v batterie and all was good .... have an idea !!!???

 

Have you checked the voltage of the TPS ?

 

Hows your fuel pump?? Do you have good fuel pressure??

 

Could be your IAC

 

I was thinking....wouldn't a 58mm throttle body be a bit too big for a 350? I've heard too large of a throttle body could rob an engine and cause it to run strange. Too much air. 58mm throttle bodies are usually used for applications some where over 4,5 or 600HP right? If you have around that much HP, you should be good with it. I'm not too sure though....i've heard these things.

 

my tps at .57volts, iac is new , i have 43psi ived test it and the trottle body was on my friends car and it was running great , also with my stock trottle body i have the same trouble... today i will go to do test on my fuel injectors could be a bad one or something....
