idle problem, cleaned AIS and still...

[lowprofile]

Hi, I'll try to explain my problem:

I have a phantom 2.5 turbo automatic.

The car has an errathic idle when I'm in drive waiting for the green light, and somethimes dies in the red light or when decelerating. When I'm acelerating somethimes a feel kind of little spark fails.

I removed and cleaned the IAC, replaced the gas filter, but car remains the same.
checked the map hose and seems to be ok, the IAC conection is also ok, the plug wires are tight conected.

I doesn't fails when cold, just after 10 or 15 minutes.

Maybe you have an idea, I'm afraid it could be the hall effect, but I'm not sure.

any help is welcome
saludos, Enrique.

this is whats happening to me on my 90 2.5 5spd shadow. Im still trying to track it down.

I dont know about you but im unable to set the AIS because my idle is to speratic.

nope, found code 23, but it was there before. Cleaned the Air temp sensor and no more codes.

I'll check this, need a multimeter. Conection is ok

The car is getting worse, now it began to fart when wot. The problem is only at normal temp. giving 1/2 gas no problem. I'm going to see how's the fuel pump working and check all sensor conections.

If is useful to know, the narrowband says AF is rich at wot.

thanks for helping me.

it was both the AIS and the SDS for me

After checking most of the sensors wires and cleaning the temp. air charge sensor the car have been ok for las three days.

I saw suspiciously loose the bottom coil wire.

I hope the problem is solved.

thanks for the advise!!

well, the car is working ok, it was only a loose plug.

..... Hits lowprofile with turbo outlet hose ..... But we never suggested checking plug tightness did we?
