My 97 Ranger 2.3 runs like crap when started then runs a little better when up to operating temp.Actron scanner says no trouble codes found.At idle live data shows this,ABST TPS %16.5 /RPM..796-836/ CALC LOAD%..68.6 /MAF lb/m .48-.51 /coolant temp..194 /IAT 194 DEG F. /IGN ADV. 9.5-11 /ST FTRM1 % -3.1 to +.8 /LT FTRM1 % 9.5 to 10.5 /FUEL SYS 1 CLOSED /FUEL SYS 2 N/A /O2S11 volts .015 to .620 /ST FTRM11 % -2.3 to 1.6 /O2S12 volts .060 to.705 /OBD2 STAT..CA. Can anybody tell me if these readings are within spec. or are some out of whack.I have already changed all plugs with right gaps(old ones were set to .055)new wires (old ones didn't have #1 wire on spark plug the whole way,and ended up arcing the metal cap out of the boot on intake side)cleaned MAF sensor with MAF sensor spray,cleaned IAC with carb cleaner.new air filter,look like there is a new fuel filter on it,new Evap purge valve(threw code with old one but now it doesn't).Any help would be greatly appreciated.Thanks.:icon_confused:
 
Nothing out of the ordinary. Record the same data when cold and running bad.
 
Drove today a little,now throwing codes random multiple misfire detected and cylinder 3 misfire detected.Any way to check to see if coil packs are good?
 
You can swap the wire to the terminal across the coil. If the misfire moves to cyl 2 you have a coil pack problem.
 
switched the wires,drove the truck approx. 60 miles.no codes popped up.Is it a fuel problem if no codes?Truck is still running rough.Changed fuel filter even though it looked new.Didn't help.Disconnected vac line from EGR and plugged it.Runs better.Does that mean EGR is bad?Checked plugs look like burning normal.Checked temp of each leg of header where it bolts to head with IR temp gun,cylinders 2&3 seem to get hotter way faster than 1&4.I don't know if supposed to check this as its warming up or after its reached operating temp.
