Ok so lets recap i had a hesitation problem.....well this is what i did to try and fix the first time...

reground everything, even boost sensor, and installed a new fule pump ( that was a waste of money)

SO now its back. I have come to the conclusion after annoying nights of contiplating weather or nto to blow my car up sell it to my friend and a gun range toy. and setting it on fire......

Ok so i need some help, my secondary injectors fire. you can hear them. but it seems like fuel isnt getting there. but every so often it cuts in and out. under load or wot, it does this if i ease the gas to 5500 6000 it starts to do it.

SO i changed the fuel pump got fuel pressure i checked. what is it, is it the fuel pressure regulater hooked to the secondary fuel rail. ? i dont know im going to the junk yard to get one becuase they just brought a new car their but if anyone has input please let me know

and if you tell me to search dont try it i have been on this forum for a long time i know how to use it cant find nothing, so thats the reason for the post thanks

car is an 86 gxl

 

ya been a memeber since 2000 this is my second account becuase i lost my email to the other one so couldnt change the password.....damn memory lol...

 

www.aaroncake.net shows the way to properly do the grounds. Besides that check the TPS. And type clearly if you want an answer. If your problem went away and came back, then I'd say 99% it's an electrical problem (grounds, sensor, etc.) not a problem with anything in the fuel system.

 

thats the website I went to. But the other day I also disconnected the tps and the car still ran as it does now with the sputter....

And what was not clear with what I typed?

 

Car runs same w/ or w/o TPS? Maybe that's the cause. I'm sure if you search you can see a procedure to test it, and/or try a new one. I dunno if that's it though.

The whole 1st post was kinda unclear, though I've seen worse. Start with a little grammar and go from there. Remember that someone else will be reading it.

 

Yea if the car runs w/ no difference between TPS plugged in and not plugged in, I'd say you have found the source of your hesitation woes......
bad TPS does cause high rpm hesitation.

 

ya Im going to get one and see what happens. Sorry for the bad gramer, I my laptop sits besides me in my truck and well sometimes typing is hard to do...now thats not what I did while driving but if one did that might happen lol... ok Ill try it if it doesnt work. Im going to maybe go carb, then possiably turbo it, I got a turbo motor coming but cant put it in until I get other things done too....

thanks for the advice guys
