My fuel injection will most likely come off my daily driver in the next few months. I hate to switch to carbs, but I'm so tired of fiddling with the FI and not getting any results.

Right now, my biggest problem is that my car won't idle when it's hot. It runs great when it's cold. But once it's reached operating temp it won't idle. I'm thinking that it's not firing on all cylinders once it gets warm. Today I had a lot of errands to run and so at first it was the usual heel-toe at a stop light to keep the rpms up. By the time I was heading home I had to rev to 3000 rpms to get going at all.

It's just ridiculous to have all these 30 year old FI parts, none of which cam be trusted to be working correctly. I have brand new TPS, Head Sensor (NAPA brand), and my MPS was tested and okayed by Jeff B. I checked my Trigger Points on the oscilloscope and they're firing as normal. I adjusted my valves this morning and they were good enough before I changed anything, and now they're even closer.

If I could fix the FI without spending $1000 on parts I would do it, but I don't think that's realistic. Grrrr, I'm just fed up
