Celica Forums General Discussion Exterior accleration problems

hey everyone I need help
here's my problem

when i am idling and tap the gas it takes a second before my rpms go up. I put a cold air intake system on it and an exhuast pipe on but cant figure out why my rpms are so late after touching the gas.

Can anyone help me or give suggestions to maybe fix the problem?

It's most likely bogging caused by the intake (very common problem). Put your stock airbox on, reset the ECU, and drive around with it for a week or so. If the problem goes away, it's definitely caused by the intake.

yeah i agree with bomber. get a tpr intake

yups...

Another alternative if you don't want to spend money on another intake is to do this mod:

Solves bogging every time.

what kind of CAI you got mad_celica?

from what I understand - some aftermarket intakes give you too much air, killing your low end tourque, but helping you in high RPM's.. if you look arround the website, find people that have different intakes, and email them - most people here are great, some of them know WAY too much..

The reason the engine bogs is because the intake is designed improperly. It's missing the little fins by the MAFS from the stock airbox, so the MAFS gets false readings. The fins help direct air up into the MAFS, instead of it just flowing around the MAFS without the fins. Only one intake out there has the fins, TPR. My intake modification I linked to above also allows you to add fins to any intake, as long as you have a stock airbox. It's solved everyone's bogging and CEL problems that has tried it, and the 1st Gen TPR CAI has done the same, since it's based off my mod (it also has the largest low end and midrange gains, and is tied for first on top end). Every single other intake out there has the potential to cause bogging due to their lack of MAFS fins, and some are so bad they can lead to a CEL.

try octane booster will clean engine and give more power while in the tank

do they make a tpr short ram?

tpr is supposidly very nice, though not CARB approved (or has that changed?) I have a AEM CAI paired with a TSRM and I don't get any bogging at all, and get a lot more power through the low end. But give the stock airbox a try and see what happens. Also are you certain that the intake is on right? no CEL's or anything right??

Octane booster = gimmick. It boosts octane like .1, so if you toss in 91 octane and a bottle of octane booster, you'd be lucky to get 91.1 octane. You'd need to fill the tank up halfway with octane booster just to get any decent increases. There is a company out there that makes something that actually does increase octane, though. They call it concentrated octane (because that's what it actually is ), and it can increase octane up into the low 100s if you mix it right. But it's worlds apart from the junk they sell in the average auto store.

Not specifically, but the TPR CAI can easily be converted into a short ram. Easy_C was doing some designs on a standalone short ram, but I'm not sure if it will ever go into production.

Nope, TPR products will probably never be CARB approved unless TPR becomes a big company like Injen or AEM. It costs thousands just to start the approval process, and if your product fails, you need to redesign it and pay even more money to get it tested again. CARB approved doesn't mean that they'll fail you on emissions testing, though, so if you have a hookup at a shop, you'll be fine. No TPR product should cause you to fail emissions as long as your car is running properly.
