My B230f powered 244 manual tranny has developed a fairly serious case of the shakes lately. It has always idled fairly rough, but since the cold weather hit, its gotten bad enough for me to actually try and figure out why.

I done the following things in the past few days:

1) Checked the O2 sensor with digital multimeter and it tested fine.
2) Removed the Throttle Body and Idle Air Motor and cleaned those, and
checked all the vacuum lines and the air intake duct for leaks, all
appeared to be fine. (the Throttle position sensor clicked right as
the butterfly closed as well)
3) Bought a vacuum gauge today and tested the vacuum from the brake
booster line and then from the port with the check valve on it. Both
times I got 20" of mercury, which is apparently good(the package said
18"-21" was normal)

I am trying to figure out what to check next. I have read that dirty injectors will cause this type of problem, they have 150xxx miles on them, w/o cleaning that I am aware of. Also, I pulled the vacuum line off the FPR and it smells like gasoline. However, if I remove that vac line and start the car, no gas squirts out, and the motor runs no differently.

What should I try next?

Thanks.
