hi gang. 88 dak 3.9 177,000 on the clock. have a miss i cant find. changed plugs,cap,rotor and wires and sounds like a wire is off but i checked everything over 3 times. any ideas? now the fuel, i think im loading up or flooding out at idle. my new plugs are all black. at high rpm it seems to run better. now im new to the throttle body set up so please be kind! no codes to speak of. inside of TB looks as clean as a whistle. any place i can get a schematic or breakdown of the TB and parts? i know folks are gonna tell me clean this and that but i wanna make sure im cleaning the right thing! LOL any help is appreciated and thank you

 

i found a broken sensor??? as you look at the motor from the front, its located on passenger side,back of motor, screwed into block behind TB. has 2 wires (yellow i think) hooked to it. it was broke almost off flush with the block. what is this and coulb it be a cause of my problems?

 

In the FAQ we have a service manual and parts manual. They should have what you need. You may have a bad fuel pressure regulator.
