Re: Constant Idle Speed Auctuator
Jusus, not seen one of those TBs for years, in fact I've not touched a 1.4 TS for 15 years, just don't get them here. Yep, that is the idle actuator (alfa Pt # 7789627), but your problem doesn't sound like it's that, I'd go for MAF on this one, so rebuild it all, unplug the MAF and then start her up, if she runs fine then, just replace the MAF. The other option is it's the water temp sensor in the thermostat housing that's playing up.
Yours is one of the first of the 1.4 TS models and that throttle body was a PITA which is why it was only used for 1 year during production.
