aright, just about got everything running good except when i start the truck cold it idles about 900, put it in gear RPMs drop to about 400 and it dies, let it warm up and it is not so bad but it does shudder when you take off from a stop.
i have changed all the sparks plugs new wires, changed the IAC, TPS, O2, cleaned the MAF with MAF cleaner, when the truck is warmed up it runs almost perfect. When the truck is running i pulled the plug off the MAF and no change. I am thinking the MAF is bad. Checked the vacuum lines, no leaks but i did not check in intake. Any help would be great as this is my daily driver. BTW it is a 90 ranger supercab with a 4.0 automatic 4x4. Thanks in advance.
