EXAUST/idle problem! HELP!!!!!!!!!!!!!!!!!!
After being helped on here by sooooo many Ranger owners, I now have a NEW problem:
After replacing a few major components (EGR valve, both upstream O2 sensors, MAF, that funky egr control box that I cant remember what it is called, & some other stuff from my previous problem, I now have a NEW one!), I now have an erratic, LOW idle SOMETIMES! It dont do it all the time, & always at different times. You can start the engine, it'll come up to 1100 rpm, then drop all the way down to about 100 rpm, then jump back up to 1100, then back down, over & over & eventually die. Turning the ign off, then restarting has no effect, BUT you can put it in drive, hold a little bit of pedal on it for a few seconds, & USUALLY, it will straighten out & do fine, for a while. Changed gas stations a few times, using NO ETHANOL GAS!
WHEN this happens, I get a strong smell of cat. converter from the exaust. NO CEL coming on either.
HELP & Thanks in advance!
