weird issue with gas pedal - Toyota Nation Forum : Toyota Car and Truck Forums

hey guys, i have another problem. the last time i posted i thought i had a distributor problem or needed a new head gasket, both were false. the only problem was that my distributor ring was broken, cost 61 cents to buy, and i paid 20 for labor so a job i thought to be in the thousands ended up cost 20.61. also my car kept dying on me and i realized that since i put in a diy intake, it turned out that i made too many connections to the new intake and it was pushing too much air into something which i forgot the name to.

but in any case, my current issue is that my gas pedal is a little hard when stepping on it. if i come to a complete stop at a light then step on the gas like i would usually (im not a lead foot so im meaning extremely light) the car doesnt move until i end up tappin in a bit hard then it accelerates fast then i can proceed to driving. the only changes that were made is that on idle or park, the rpm stick would be around 1 or 1.5 rpms. so the mechanic took it upon himself to bring it down below .9 to save on gas but i think it has caused my gas pedal to be hard. the other change is that i purchased a smaller intake for the car but i dnt think thats the cause but im just listing the changes as a good driver i think i am.

i hope someone has a suggestion on what may be the problem. i know cams are usually at 1 rpm and i dont know if being so low that its causing acceralation problems.

Do the person did your distributor redo the timing? If he just put the O-ring without doing the timing that will cause your idle to be rough. Just a thought!?

Have you tried idling the car and mess around with the linkage under the hood to see if it's unusually tight or something?

I'd start there.

well i dont think he redid the timing, how can i go about doing that? maybe by myself if its not too complicated. i already know how to remove the cap and distributor

i tried idling the car and its a worse start off when i do that and i checked the throttle which is what the mechanic set back to drop the rpm to .9

If you're talking about the idle speed screw, then you may have found your problem. You're not suppoed to fuck around with that, it has been setup according to how the car's suposed to run. If your car is not idling good and you do this, you did not solve the problem and lost the proper factory setup once it is solved.

Anyway, messing around with the idle screw will affect your gas pedal.

EDIT : Since it's a DIY intake it won't have the same air flow than factory and everything so maybe you will have to live with it in the end or ajust your linkage for smoother operation.

Spdlva, try cleaning your TBI and air butterfly. Dirty butterfly could cause a sticky throttle. Use throttle body cleaner from a can, and old toothbrush. And plenty rags. Theres about a thousand posts on this subject here, some from me, because this is a very common problem with Camrys.
And the fact you found an honest mechanic is a miracle. Here in So Cal they always try to charge you for everything but the kitchen sink. Another reason i do it myself whenever its possible.

well it wasnt me who fucked w the idle speed screw. i went to my uncle's mechanic and i didnt want to go but my fam keeps buggin me to go cuz he's so great so i went so they could shut up and while i was explaining my situation w a previous problem, he took it upon himself to whip out his tools and fuck w my idle screw and now its acting up. i told him the car is probably actin funny cuz of that and he claims its not and blamed the intake. all i know is that i didnt ask him to do the work on the idle and he did it and now my car isnt working properly. guess i will end up going to toyota to fix it for me, thanks for the info, i know not to go to this asshole anymore

spdlva2nv4eva · 05-19-2006, 11:37 PM

i will do a search on cleaning the tbi and air butterfly, thanks for the heads up

Yes clean everything, but I don't know man, just take a look at the screw. He had to bring it down so I guess the plate had to be shut tighter, hence pulling the throttle cable along the TB pulley. You could just turn it to make the plate open more bit by bit until it gets back to 1.5, and modify the intake accordingly. Or leave the screw where it is if the car idles fine and just ajust the pedal cable...The guy might not be an asshole but he didn't think about that. I'm no car wizz but you still have a custom intake on there so some ajustment might be needed...

Is it just me or is this the hardest four sentences in the world to read?

my apologizes for the hardest four sentences you have ever read, i was just frustrated with the entire situation. im glad you guys were able to help me out. it seems the pedal needs to be adjusted by the throttle.
