Cobra Intake problem

sgwinn · 06-03-2007, 09:24 PM

thanks. Buddy of mine thought a new chip reprogrammed to add more fuel at lower rpm might work.

Don't waste your money on a chip right now, it's not the issue and it is rather expensive.

Back when I had a stockish motor with an explorer intake which is basicly the same thing as a cobra intake I didnt notice any negatives just positives.

By changing only the intake. I went from a stock intake to an explorer intake and went from a 14.79 @93mph to a 14.46 @95mph.

The bog/loss of low end torque is not intake related IMO.

thanks. you had said to also check the TPS voltage. what is that and how do I check? forgot to mention that i also had the heads cleaned up, shot peaned, mangafluxed and valves cleaned and new guides. could something in the head not be synched up right causing the hesitation? thanks.

Sounds like timing to me, what's it set at right now? All the chip is gonna do is bump your timing anyway,

Figured it out. Stinking gasket was not the right one. started hearing noise like the fan belt was old, dried out and squeaky. had it replaced (needed to anyway) and noise was still there. took it in and they diagnosed the vacum problem and determined which gasket was causing the problem. (had to take the intake off to tell) ordered the correct intake gasket, replaced, and no bog at all. runs like a champ.
