I have a 94 EG and put an OBD 1 LS in it, and when I started it, I have to keep on the gas to keep it running... I have a Skunk2 intake manifold and NGK spark plugs, but should I do anything to the fuel system for this setup? I also have full exhaust, JDM ITR header, and 2.5 all the way back...

Any suggestions?

 

Sounds like a possible issue with the timing of the motor. Did you put a light on it? If so, then could be sensor related.

Mass air flow
TPS
IACV
(all electrical connectors are connected?)

You have a CEL lit?

 

Yeah, the only CEL I had was the coolant temp. So I wasn't sure what was going on. And the timing should be right. I haven't put a light to it, but everything else is lining up.

 

sounds like its some sort of sensor problem. What rpm is your idle at?

 

sounds like a tps sensor possibly... did the ls motor run before you got it... or did you get it from some shaddy motorplace.

 

I got the motor from H-motors online. It's the third one I have bought from them, never had a problem. The motor, doesn't idle. I have to keep on the gas a bit to keep the car running.

 

My geuss would be in ur feul system to. Maybe check ur injectors rail and feul pump. Maybe sumthins clogged up really good???
