ok so maybe my tbi injectors are bad
 
i got real mad yesterday when my truck died so i popped off the air filter housing
and i started my truck

i watched the fuel coming out of the tbi and i noticed that it looked like someone flinging paint everywhere not a nice even flow
so i dumped some injector cleaner in it and checked again today after work same thing
i know that eventually injectors go bad no matter what you do to clean them out
is the spray sposed to look like a nice even cone shape or a steady flow

if it is my injectors i wll have to wait as they are very expensive
any one have a clue as to how the spray is sposed to look
and again my fuel pressure is normal to the filter and tbi

If im not mistaken its supposed to be in a cone in a somewhat mist

thanks that was what i was thinking but wasnt sure
so i guess i know what im doing this weekend
any ideas of a good brand to go with for the injectors
as i dont wanna be spending money down the drain in a month or so

I always went with Bosch but they are a bit pricey but they are good quality along with their plugs (which work great)

but there is a product that you bolt to your fuel line that actually cleans your injectors. Ill see if i can find that for you

cool thanks ive been shelling out 4 dollars a week for injector cleaner so anything that i can use more then once would be great and i think i will go with bosch as that parts company has allways been good ive never had a part from them go bad yet

and after the mechanical problems are debuged its body work time on the beast so ill try to take pictures as i go along

If i read a couple sources right seafoam should do the trick.....

I have no clue where to put it on your engine but alot of places said to do it in the brake booster which is where i put it

you can put it in your gas tank or run it thru your booster line like you said
and i do have a bottle of seafoam so i can try it later i just dont have much gas left after today
or pcv valve or any vacum line that goes to the tbi
