>To me it sounds like your Idler control valve has gone bad, this is very common to our cars. The perpouse of the valve is to bypass the throttle body, the throttle body is controlled by your accelerator pedal when you have your foot of the pedal the throttle body is completely closed. When it is closed there is no air going into the engine, thats were the IAC valve comes in, it lets the air enter I'm assuming you also have a rough idle? thats because the valve is filthy and can't maintain a good idle, it maintains a good idle by opening and closing rapidly.

It idles fine, no problem what so ever. The iacv is clear, ive had a look through all that and its fine, Ive fixed the starter motor today and now theeres no sparking but still having cranking problems car died again today and wouldnt even roll start, I had to get it towed from where i was. Im am pretty sure its a distributor problem but where to get one that doesnt put me completely out of pocket i dont know. Getting sick of this car now.

lol yep, know that feeling well needles.

I changed the igniter with another used one from a camry. It didnt make any difference so i changed it back to the original one from my car and I got it started, very low idle, revved it a couple times and about 1 minute later it died again and would crank but not start again. its definatly got fuel, I still am getting no spark or atleast a very weak spark. so far the Distributor, cap, coil, rotor, sparkplug leads, igniter, starter motor and battery have been changed... Im fresh outta ideas

found a bit of oil on the spark plug in the 1st cylinder..

I'm having a similar issue with my car. I'm thinking it may be the distributor as well as ther eis some oil on mine. I also already replaced the igniter & the fuel pump so I know its not those two things.

The problem with my car when it would randomly start was the temp sensor located at the rear of the top water hose. When I would wiggle the wiring harness car would start . then die. Well I found out the temp sensor there (right hand one from front view) was cracked inside after a new one it never happenned again. Worth a check

Today took the car (after roll starting) to the shops and came back, no worries. Went to roll start again and it didnt start. Tried my luck at cranking and the car started. Put it into first and went to take off and the car died, no electrics worked, no cranking, NOTHING. Disconnected the battery for ten min and put terminals back on, negative then positive, as I was putting the positive terminal back on it sparked HEAPS, far more than normal, and smoke started coming out from underneath the startermotor (not from the starter, just the area) aswell as melting a bit of the + battery terminal. I have no idea whats going on and I really need some help...


if you have smoke coming from somehere and smell a burning smell, you have serious problems. and it doesnt matter what terminal you connect first.

Its not the IAC, that has nothing to do with whats going on here.
