error codes help
Its an 89 305tbi .030 with 5k miles on the engine. have had a lot of electrical issues with it in the past but have fixed them up for the most part. didn't have any problems with it for a few months until today. here is what i got
13. Oxygen sensor signal stays lean during warm engine cruise
23. Low temperature at manifold air temperature sensor OR Throttle position sensor error
33. High voltage (low vacuum) at mass air flow sensor (or MAP sensor)
43. Low voltage at electronic spark timing circuit
54. Low voltage at fuel pump OR Low voltage at Fuel pump relay OR Output failure at quad driver module
I have have the codes 13, 23, and 33 come up in the past. i have replaced the 02sensor and the wire for it. I have replace the air temp sensor and the wires for that as well. and the same for the map sensor. i use to have a huge problem with the knock sensor going off but lately i it hasn't shown up. but code 54 ive never seen the past year and half that ive had the car, and today the car started acting like it was running on a couple of dead cylinders. made a horrible noise and didnt want to get up and go. I love this car, and it was treated like **** before i got it. whoever had it did ntn to take care of the car and almost everything had to or has to be replaced including the entire interior. i have put a lot of time and money into this car and just want to get it right. Thanks in advance for all your help. I want to no what all its going to take to fix all these problems for good.
I replaced the distributor cap and rotor and all sparks today when it started acting up, and it is still running like it isnt firing in all cylinders. everything is hooked up.

Re: error codes help
Looks like a bad ground or more. Check the battery cables for breaks. Check that the bolts are tight.
Check the grounds that are attached to the back of the head(s). The bolts need to be tight and the head surface clean.

Re: error codes help
Ok, one of the battery cables going to the starter has some bare spots in it where it rubbed up against something in the past. but it hasnt been touching anything since then and its been a few months. could this cause it to act like its running on a few dead cylinders out of no where like this? what else could this have messed up on the car that im gona have to replace as well?
