i got the kit off and im back to stock but now the car appears to be running rich. The exhaust has a heavy smell of fuel. Any ideas why that is and how i could fix it?

 

Did you reset the ecu by disconnecting the Neg terminal on the batt?

 

running stock injectors?...its going to take a couple of days for it to return to normal...you can speed things up by driving around roughly 40 miles...it helps

 

Disconnecting the battery will be the quickest way. You need to reset your fuel trims.

 

wouldnt everything reset once he pulls the piggyback off and the kit off, puts back stock injectors and all other stock parts? the monitors would reset back to normal after a certain about on driving

 

oh stock plugs too! but yeah reset the ecu and its should clear the fuel trims it made with your tune

 

yes both ways work...resetting the ecu or just driving around for a bit will do the trick.

 

Did you ever upgrade your fuel pump?

 

na still have the stock pump. ive reset the ecu and its still rich. im also getting a cell im going to find out what code its throwing tomorrow. I guess that could be causing it to run rich we shall see

 

yes check that out asap, plus better to run rich than lean =P

 

mafffffffffff

 

yeah check the code, it could be your maf or your O2 sensor went bad.. But try driving the car for a bit and it should adjust the your fuel trims to where the ecu wants it

 

So the code it's throwing is p0171 system to lean. Any ideas

 

Resetting the fuel trims is not done by simply disconnecting the battery. You must discharge all the capacitors in the ECU first. Disconnect both battery terminals and touch them together for 2 or 3 seconds. Done. Reconnect and the car will be set to relearn fuel trims. Also check all the work you did and make sure that there are no loose vac lines.

 

Checked vac lines. no leaks. Gonna Clean maf and reset ecu like don said

 

Update: No vac leaks and i cleaned the MAF sensor but it was still throwing the code. So i replaced the primary O2 sensor and that seems to have fixed it. Ive driven for like 30 miles and the code hasn't returned. It would come on almost instantly before.

 

maybe that was ur problem all along with the turbo kit

 

yes.. or maybe your tune made your O2 sensor to fail prematurely

 

o2 sensors and be fouled too

 

na turbo seals are bad. the old o2 sensor wasnt mine and it had been sitting for quite a while
