22re help, hard to start, runs great once started, codes 8 and 27
Well I have a 1987 4runner with a 22re. Engine was rebuilt 5k ago with new head etc. About 6 months ago I had to phurchase a new afm and adjust the tps. Just today it started to be extremly difficult to start. If i really work on it wihte the gas all the way down and can get it to start eventually and if i rev it up for a second before letting off it runs and idles just fine. I have been gettign an average of 18mpg with no drop lately. Plugs look good cap and rotor also arer good. When i just the ports under the hood im getting a code 8and 27. Any help would be apreciated.
Code 8:

OPEN OR SHORT IN INTAKE AIR TEMP. SIGNAL

Code 27:

try unsrewing the gas cap and put it back on. it might be vapor lock
i had the EXACT same symptoms as you and i did that and it started normally
i have an 86 4runner btw
