no knock tuning.. impossible for me.. ideas why?

[TType84]

hey guys.. think im going to go the propane route very soon..

cause my car lately has been acting gayyyy... gimmie some ideas guys

1st gear, idle - 5800 no knock
2nd gear no knock
3rd gear, knock
4th gear, knock

i think my fp just isnt keeping up for some reason.. maybe the pump is tired, maybe i need a new fuel filter (going to try that tomorrow maybe)

but th car is FINE until it shifts to 3rd and then WHAM i hit a wall of knock, i have to be careful on the highway to just go WOT to speed up, because if i roll on the throttle it will knock like crazy..

ideas? fp is high more like 46psi or so.. shouldnt be a problem caused by my cause this DIDNT use to happen

Do a compression and a leakdown test...Also, do you have an oil pressure gauge installed, and if so, what is your oil pressure idling in gear, and at WOT???

Whose chip are you using and what timing at WOT??? I think I remember you saying it's a Jay Carter chip??? Has this been gradually showing up, or did it just all of a sudden start up???

There is a bunch more load on the motor in 3rd and 4th gear than in 1st and 2nd...Just how much knock are you getting???

 

[TType84]

i can go wot from a stop

1st-2nd gear no knock
only maybe on 1-2 shift my car shifts VERY hard

i have an oil p gauge havent gotten around to installing it (bc im lazy )

maybe i can do it tomorrow, i will if i can (no holder though it'll be taped up somewhere haha..

jc chip is 17* timing

and no, it didnt use to kncok this bad.. i killed a FP reg before so maybe i killed another one.. so i will borrow a fp gauge on a line and check it out.. wish i still hd t link bcause then i could check o2's i really wann aget an o2 gauge but.. $100 right there.

seems gradual..

hmmm...maybe it is the fpr...

If gradual, maybe you've just got a little more carbon buildup in the heads than what used to be...What kind of boost are you running and what oct???

 

[TType84]

have had boost at 15psi for god knows how long.. havent touched the WG

93 octane

...should i spray a lil water @ idle.. like out of a spray bottle into the boss on the stock maf pipe.. maybe atomize some carbon or what? i wish TEC worked for us..

Nick make sure your vac/boost line to the regulator isn't leaking.

Also - how are the plugs? Pull them and check the gap.
