Engine Problems

[Madjak]

I have a 96 BZ touring Corolla Wagon that is doing strange things. If you drive it for a while till it heats up then leave it for about half an hour an go for a drive the engine stalls out when you take off I have checked the codes an came up with a oxigen sensor fault. Replaced the oxigen sensor an it was good for a couple days but now its doing it again. Replaced so far Plug, Leads. Oxigen sensor , fuel filter & Throttle position sensor. Rechecked codes now it has (No Igf signal to ECU for 4 consecutive IGF signal during running Code 14). (Open/short in heatercircuit of oxigen sensor for 0.5 seconds. Amplitude of o2 sensor reduced to 0.35-0.70v continuously for more than 60 seconds Code 21)&(o2 sensor output in less than 0.45 volts for at leased 90 seconds when o2 sensor is warmed up and 1500rpm an above) Does any body have a clew

Wow. That's a tricky one.

All I can think of is a problem with the ECU itself or perhaps the mass airflow sensor (unlikely)

Do you have any modifications to your motor?
