aright i am about ready to shoot the truck, first of all it is a 90 ranger 4x4 with the 4.0 and the a4ld. if the truck's gas is above a quarter tank the truck will run great with no issues but when it gets below a quarter tank it started to run like shit, the idel goes down to about 600 and jumps up to 800 while you are stopped in gear, with more than a quarter tank the idel is about 800and steady. when you take off you can see a puff of black smoke from the tailpipe so its running rich, did throw a CEL will pull codes tonight, so far i have cleaned the MAF, replaced the O2 about a month ago, it has new plugs and wires,new TPS, new IAC, new fuel filter,new air filer. i will post the codes tonight,any help would be great as this is driving me nuts
