Gta holdin back

[transgta]

My 89 gta 350 has had issues for quite some time ill run u thru. Its got 30 k miles everythings like new. Ive put 3 fuel pumps in since 89 dont kno why they jus seem to go. Recently with brand new pump still was surgin after i let off hard acceleration. Just didnt have its power..After all these years i put new fuel cap on it ran like new better than ever.. Now two weeks later all the sudden when u hammer it sounds like ur really movin but u can jus tell its holdin back.Then it hits second sooner than it should hits so hard spins tires jerks ur neck. From 2nd to third it dont shift til 5 grand but still not the power it should have. Tried yet another fuel cap nope not it. I have no ideas left please help..

is the ses light on, how dose the maf sensor look or dose it seem to "rev" good in park or neutral
also what about the fuel filter or look for a pinched fuel line

[transgta]

When i rev it still doesnt seem right. To the average person they may say it does but u kno ur own car. Not sure what ses is but theres no lights on no codes period. Everything on this car is like brand new never seen rain. Jus put fuel filter on along with new pump an sending unit. It acts like a clogged cat but there isnt one. Was told a canister under hood is some kinda vent for fuel to dont kno anything about it.

Jus messed with yhat canister up by headlight when i messed with one of the hoses fuel came outta the line. im thinkn it shouldnt.

[jason-1995fbody]

normally fuel shouldnt come out of that line that is just to vent fumes as part of the emissions system dont know if thats the problem thow but cork it off and go for a drive see if it changes any thing

and just FYI ses = service engine soon\check engine or what ever light your car has it varys

ill try thanks.roads r damp been rainen here n bargersville but ill try if not please chek bak later..THSANKS DAVE

[jason-1995fbody]

yeah it sucks raining here to just got mine running again today not much fun to just listen to it run in the garage

[transgta]

Unhookd big line plugged it drove same. Unplugged it left it open drove got gas out of it quite a bit. i dont understand why im gettn gas period if its a vent line

[jason-1995fbody]

did you filled it with gas recently

[transgta]

The day i put cap on filled it drove few hours. next time started it it was messed up. Then put gas in again since then.. Tryin to figure out if i have wrong gas cap all the parts stores say not vented but the original has a spring an some kinda metal ring in it. Im wonderin if the new nonvented cap has forced fuel to cannister but took a while to get there. But anyway why would i have got one good day outta it

[jason-1995fbody]

i dont know about the cap as far as i know the canister is filled with charcoal to filter the hydrocarbons from the gas fumes rather than them going into the air (emissions control) now liquid fuel getting there usually is from "topping off the tank" too much


on another note what is the fuel pressure with the car running, not running also pull the vacuum line from the pressure regulator and see if it is wet inside the line

[transgta]

Ok i ordered an oem cap fuel pressure idles 60psi rev only drops to 50psi think thats good. i did take vacuum line off regulator the other day did seem a little moist in it. Does this mean regulators jakd up?

[jason-1995fbody]

60 psi seems high usually a bad regulator would send fuel though the vacuum line if you tap the line on a piece of paper and the paper gets wet drops on it then i would suspect the regulator but i still dont know that this would cause your problems

[wrightz28]

60psi is WAY high.
