LIMP MODE PROBLEM SOLVED - I THINK

[bronsin]

15 year old battery? Hard to believe but time for a new one!

Do you know anyone with a similar car you could swap parts with? I fixed my sons 2000 Echo by treating the airflow sensor with my 2009 Yaris. When I did His code went away and mine through the same one he had. A rebuilt airflow sensor solve the problem.

Bronsin, Do you mean the MAF (Mass Air Flow Sensor)? I did clean that a while back, didn't seem to do much. No, I don't know anyone with a similar vehicle. My battery was 5 years old, not 15, sorry, made mistake reading age there, just topping up a new replacement. I think old battery was ok actually but, have to eliminate all possible causes of problem.
Problem seems to be temp related, like turning on the interior heater, but that wouldn't explain the fault codes. Could be dodgy wiring to Throttle Manifold or ECM.
I took off and checked the Gas Pedal earlier this year - it was part of the Toyota recall and has been shimmed with a green tick sticker so should be ok.
This model has a rep for bad idle / rough running/ limp mode problems I found out anyway. Toyota at fault here.
I did notice the black plastic filter housing that contains the MAF and fits onto the throttle body was cracked, but I put some Duct Tape to cover the crack, I should replace it really.
