Had a long block installed and now the cold idle is 2100rpm's.After warm up idles fine at 750-800 rpms.The garage said they made no adjustments.Any suggestions would be much appreciated.Checked for vac leaks and didn't find any.The last two long blocks did not have this issue.

 

sounds like a defective long block then. hope you've got a warranty.

or, you could GO TO GOOGLE, TYPE IN "22RE COLD IDLE" AND READ EVERYTHING YOU SEE.

it will look like this:

Low idle on cold start - '88 22re - Toyota 4Runner Forum

Thanks in advance for any help. I recently bought an '88 4runner 22re. Absolutely love it, but am having an issue with cold start.

GOOD LUCK, WE'RE ALL COUNTING ON YOU

 

My truck has low idle or no start at all...

My 88 toyota 4runner when it's cold, winter, or in the morning in summer, it either does not start (winter) and if starts (summer/winter) does not want to stay on. I have tested, checked and cleaned: air intake, cold start sensor, air control valve, the sensor located after the air filter, forgot the name...all according to results are good...I do not know what else to do. I have to stay in the truck for a few minutes, at least 5, in order for it to stay on, on its own, very low idle almost stalling. Once it's warmed up, it has a good idle. If turned off and then on within one minute while warm, cranks very low idle like I just cold started it and I have to accelerate it in order to get back to normal idle again... Do any of you guys have had a situation like this? I have read similar issues, checked and tested what was recommended and still have the problem. Thank you in advance. I hope I can get this nightmare out of my way soon. I have dealt with it for the last 4 years...
