it is a 92 TPI and it started to run like crap. after some research on here i swapped the ignition module under the distributor cap. on the 1st ride i got the same codes again.

I do not have a wiring diagram but is there a common wire that would cause all three codes?

the 42 code comes in as soon as i start the engine and the other two after about a minute or so of driving.

I am lost at this point so any help or suggestions would be great.


what actually triggers the 42 code? it is low fuel pressure but there is no pressure transducer???


thanks
