Murphy's Law
I bought a used engine after i broke my crank, the engine came with a newer MAF transator and a questionable MAF sensor. So i bought a new sensor and got the car up and running, can ran good and all of my scanmaster numbers looked ok, BLM and INT both held at 128. Now while i was in the process of going over everything i opened up the translator to see what it was set at, the translator setting were for a extender chip and a 3.5 MAF. I changed the settings to match my setup Turbo tweak chip and 3'' MAF, now my idle surges when in park it will drop from 900 to say 600 and come right back up and my BLM is at 142, INT fluctuates but today it was at 128.
I have had this new setting for a week or so and drive the car 10-20 miles daily so its had time to learn also reset the computer. My logic tells me to put the settings back where they were but what would cause this ? At this point i just want it to run right but i know the previous settings are not correct for my setup. Oh i also added 10% more fuel via the translator and have played around with the fuel pressure, neither of those seemed to make a difference. Also not sure if this is related or not but i noticed sometimes when i come off the throttle my rpm's drop a little low then come right back up, for instance when in third gear or overdrive if i let off the throttle the rpm's will drop to around 900-1000 and then go up to 1500 where they would normally be. I cant remember if this was happening before i changed the translator settings or not.
Anyone else seen this before, what are your suggestions ?
