If any of you remember I had a misfire problem with my 96 WS6. After replacing almost all of the ignition components I finally had a chance to get it on a snap-on scanner to read the misfire counts. Turns out cylinder 4 was the culprit, and after checking compression/spark on it I determined it was most likely the fuel injector. Seeing as how I have intentions of modding the car further I picked up and installed a set of SVO 30lbers.

Now the problem: Although this fixed 98% of the problem, there is still a SLIGHT hesitation at low throttle. ie: 2100-2900rpms. All other instances the misfire is fixed. Could this be caused by the fact I did not switch over the tune for the bigger injectors yet?

If anyone has any thoughts on this nagging problem please let me know, I appreciate any and all input.

*EDIT*
Just thinkin out loud here, could this possibly be due the the crack I found on the TPS sensor flange?

 

umm ya your computer is tuned for 24# injectors and the 30# svo's are rated at a lower pressure so ya you need to tune the computer for them, you will be running very rich, block learns are probly maxed out

and id replace that tps sensor right away too
