got trouble codes...now what?
Folks, I need to know which direction to go now? Got the codes out of the 92 eb bronco and the list is rather lengthy. This is after trying to reset the codes the day before.
113 -act
118 -ect
123 -tps
126- map
334 -dpfe/evp
337 -dpfe/evp
634 mlps
637 tot (transmission oil temp sensor)
113, 118,123,126,334,337 all seem to related to each other for all of those sensors to be bad, but can't seem to find anything wrong with the wiring. the truck starts and runs the same with or without the MAP sensor plugged up to the electric (rough idle with black smoke). Would one of these cause problems or codes with the rest?
634 Just replaced the MLPS to minimal effect. The truck idles much more roughly when the selector is in park and better in "N". Will look at the mlps again tomorrow to make sure it is adjusted correctly.
Any advise or direction would be greatly welcomed.

yeah sometimes one messed up sensor will cause the engine to run bad and the computer will throw lots of codes
black smoke means its running rich, if its idling bad i would start by taking of the TB cleaning it and the iac and replacing the tps
that solved my idle problem, (the first time anyways)
