2003 Mazda B2300 Q&A
2003 Mazda B2300 Question: miss at idle but runs good.
i have a b2300 and it started missing pretty bad at idle but once i take off it drives good, it had a code for miss of course so i replace the plugs. my question is i can spray sum b-12 by the power steering pump and the idle picks up like it should so i replace the gaskets on the intake pletium. replaced hoses also, put everything back and it still does the same, has anyon ever had this problem? need alittle help thks! - williamd96
Find and repair your vacuum leak! That's it. Maybe use a straw on a can of WD-40 to pinpoint it more. Just dont spray it on an ignition source! - pushrod
Engine misses through all five speeds, idles beautiful, runs good wide open.
