Car will remain running after it warms up, but not happily. Of note, if I remove the cover from the smaller vacuum port to release some of the vacuum, it actually runs a bit better (rpm goes up a bit and doesn't sound as rough). If I open the air flow meter and manually reduce, it runs smoother still...
I removed the AFM. Connector to throttle body seems good. No cracks. I then sealed that, hooked a tube up to a vacuum port and blew in smoke from a cigar. First of all, bleh. Been a long time since I smoked a cigar and I remember why I only tend to do so when drinking...
There does seem to be a small leak in the throttle body. Not at the gasket, but where the throttle goes through the side. Not large (takes a while for to equalize), but does release pressure over 10s of seconds. Is any leaking at all a bad thing? If so, is there a way to seal that section of a throttle body? Or do I get a new one?
Next, I'll start learning how to test temperature sensors. Bought a good mulitmeter. Now just need to learn to really use it (and what to hook it to where...)
