well to update this thread and to help others who may have this similar problem in the future and are searching for a solution, here is where i standhere is what was printed out verbatem:
vehicles have one or more of these components. Engine load or the air volume entering the engine measured by these components. The computer has recognized a return signal error.
Probable cause
1.-vacuum hose off, cracked, or passage blocked
Engine mechanical timing condition
2. throttle body intake tube loose, off, or cracked
3. map defective
4. maf dirty or defective
what i have trouble shot so far
replaced vacuum lines and triple checked these and did the wd-40 trick to pinpoint a vacuum leak- ok
has aluminum intake tube, and checked the tube fitting for the throttle body and is on tight- ok
replaced maf already with no change and checked the voltage at the maf-ok
so could be a vacuum line still, or the map sensor
after well after have replaced all the vac lines, replaced the maf with two, and replaced the map sensor i have not solved my issue. so i am left standing at this point:
before this issue i replaced the stock tb, with a similar stage 1 ported tb with no screen and swapped my IAC and MAF sensors over to the ported unit. i noticed that this issue began about a week after i swapped the TB. so after replacing the map with no change i am doing some process of elimination. i put the screen back in the TB along with a known to be good TPS sensor from the stock TB. if no change then the stock TB will go back on to see if that cures the problem
