what all will make a 93 3.4 v6 run rich

 

Many things can make an engine run rich. Have you scanned the ECM for codes? However, the usual culprits are: misfire, bad pressure regulator, stuck open injector, bad ECT, bad IAT, bad MAP, clogged air filter, bad MAF if equipped, restricted exhaust. Have fun.

 

i have scanned for codes but no codes were found,i pretty much have replaced all sensors you stated ,fuel pressure checks fine as does ignition system,my next move will probably be new injectors

 

Make sure the control leads to the injectors are not shorted to ground, as that will hold the injector open at all times. Your engine still uses batch fire, so that an entire bank is fired at one time, a common control lead is used to fire each bank.

 

There are about 21302 things that could make you run rich... I don't feel like listing them all =P

 

Then why post anything at all then
