well, I've racked my brain trying to figure out why my car is being such a pain in the butt....
it idles high(900-1000RPM) and with a studder every 0.5 to 2 seconds randomly.
I checked my plugs(NGKs) 3 weeks ago, and although they looked used they looked fine. I checked them again over the weekend and they look like I took the cake frosting to them, filed everything to a 45 degree angle, refrosted, and regapped them to 0.5 inches. needless to say there's now new plugs(Denso) in the car. so why now is the car running lean?
The TPS I checked, 3 times, I have a spare TPS, it checked fine (and exactly the same as the first TPS) and is installed on the car for giggles.
The ISC was checked, all three of the ones I have, they all seem fine.
new cap and rotor, wires are almost brand new(toyota)
I've been over the vacume system 3-4 times and can't find any leaks. new lines ~1 year ago.
O2 Sensor is less than 1 month old.
the timing is set to something rediculous because at 10 - 14 degrees the engine chokes, hesitates, and has No power. (distributor 1 tooth off?) I "Know" the timing belt is right.
Injectors I haven't fooled with yet. Check connector doesn't work.
I'm sure I've forgotten some things I've already tried, but please, throw all the ideas to guys can think of.
TIA,
Mike
