• Open or short in IGF circuit from igniter to ECM
• Igniter
• ECM

ONn/a

Yes

It seems you may have a problem with your igniter. Did you ever get a TSRM for your Supra?

Also, please re-check those codes. I don't think it's possible for the ecm to give a single-digit code. Perhaps it's 22?

hi mate, but if it's code 22, should the time gap of those flash a bit longer? I did upload to youtube, would you mindhave a quick look for me?
