Well I switched my intake side coil pack 1 for 4, 2 for 3 and I noticed a big differance. It started much faster, ran smoother, and definatly has a little more power! I can cruise at 45 in fifth and it has plenty of pull, no need to downshift any more! I have to say that many other mods were done to my 2.3. Electric fan, Removed entire EGR system,Installed EGR elimanator circut in ECU. Cold air ram intake, Bore matched entire intake MAS to head. Free flow exhaust with no cat, Thrush glass pack, silencer tip, all 2"
Awhile back I had an always rich code. I tried everything I could think of to fix this and got many suggestions here but the only thing that fixed it was to side gap my plugs, an ol'racer trik, look it up! a cool alternative to those gimmic plugs like E3 etc... and much cheaper.
Before all these mods I was gettin bout 15 mpg, after changing every sencor and cleaning the MAS got bout 18 mpg. after intake & exhaust, 22 mpg. And after switching plug timing & side gappin the plugs, 26 mpg.
I would say the most important things were the o2 sencor & a really clean MAS sencor. these two things are in charge of what happens with every thing else. I reset the ECU after these two installs but I havent touched it since. The ecu seems to adjust it self really well on its own.
I've been playin wit this ranger 2.3 for awhile now and I dont think it can get much better than it is. Best runnin motor I ever had! Thanks Ranger Station & every body for all yer help! It's been a learning experiance for me and I couldnt have don it with out ya! I'm a Chevy man by birth but this ford is excellent!
