It lives!!! The Haynes manual was not wrong on the firing oder. They must have fixed it. It also had two broken spark plugs that was causing my problems.

Now it runs and is an awsome motor! Here are my final problems, I hope:

Check engine light comes on every now and then while driving. Stays on for a minute then goes out.

Codes: 173, 177, 179, 188

Any suggestions?

Also it idles so low that it wants to die and does most of the time. I hade to put a little piece of folded tape under the throttle assembly just to keep the idle up to where it won't die. Maybe bad Idle Air Controller?

Thanks for any help.

All the codes are explained in the Haynes manual.
Looks like your o2 sensors are reading;
173=rich right side
177=rich left side
179=rich right side
188=rich left side
 
codes

173= hego [ho2s]sensor fault rich 177= hego [ho2s] sensor/fault always rich 179= fuel system at lean adaptive limit at partial throtle / system rich 188 = fuel system at lean adaptive limit at throttle / system rich
