In 4th gear, if you stomp on it, it bogs down, other than that it runs normal.

 

Seafoam it!!!!

 

NO! NO SEAFOAM! that stuff is evil especially if you don't do it right!


so it only bogs in 4th? 1-3 works perfect?

 

come Monday im gonna look on the Mitchell 1 program in class and look up your trucks senors and their specs


can you put your specs on here
its a w150 right?
318/360
its a 91?
stuff like that
thanks

 

Sure, Its a 1991 W150, 360 with NP435 4 Speed Manual. Used to be a 318 Auto, but I converted it last summer, still running the 318/auto computer. NP241 T case with Chrysler 9.25 rear and a dana 44 front. I think that's all that really matters, Thanks a ton.

 

alright thanks ill try to figure something out for ya

Yes, but my guess is because of the gear gap which drops the revs, it will do it in 3rd if you slow down, don't downshift, and try to accelerate. It seems that once you pass 1400 revs your fine, but if you stomp on it and your under 1400 it bogs down. Once it warms up its a little better, but it still bogs. What is the best way to test an O2 sensor, I know they are pretty delicate.

 

Be sure to check the fuel filter too, This might be offtrack but how did you get the computer to work with the bigger engine?

 

ok so Mitchell and alldata are pretty much useless... ive tried the past two days and it wont give me anything.... its like your truck is a magical being that only appears on a full moon for an hour if its Friday the 13th in june and its raining... like wow! im just gonna go off the possibilities of my truck:


coolant temp sensor: if its bad and registering its way cold its gonna dump fuel since its trying to compensate for the relatable air temp then


injector stuck open: if its open its gonna bog and dump fuel but at idle I don't think if one of them was stuck open you'd be able to tell


one more question: when it bogs is there any smoke that comes out the tail pipe cuz if theres black smoke billowing out its wayyyyyyy too much fuel and thatd be your problem


02 sensor: I class we use lab scopes... back probe the wire with a t-pin or a paper clip or something like that... idk if you can get ahold of one and ill keep trying to get the resistance specs of the darn things but till then idk what to tell ya about those


if you could crawl under there and tell me if its a one wire or 2 wire o2 sensor that would help a lil

 

Yeah, tomorrow I'll tell you if its a 1 or 2 wire sensor. There isn't any smoke out of the tail pipe. I know the coolant temp sensor worked as of last September. I have tried to use alldata before, and it is very light on the info it gives on my truck.

beakerztoyz, there is nothing you need to do to get the 360 to run of a 318 computer, just plug it in and your good to go. Because the 360 has bigger injectors in the throttle body, the fuel injection is proportional. So if the computer wants to inject X amount of fuel into a 318, the larger injectors in the 360 will allow the correct amount of fuel to be injected. Thats probably really confusing, I find it really hard to explain over text.
