I just recently bought a 92 VR4 the car is beautiful only one problem. when i put my foot straight to the floor the car bogs out and the turbos can not spool. so when i let the rpms raise and then i slowly push down the car has alot of power but even if i let the rpms raise and then put my foot into it the car bogs so is there anyone with this problem that could help?

How old are the plugs and wires? Try doing a boost leak test.

 

the spark plugs were changed like 5000 miles ago and the wires are the originals but i had them checked when i got my oil changed and they said they were fine.. could the wires really cause that problem? so their might be a leak in the boost lines? is that expensive to fix??

 

How many miles are on the car? Replacing the wires might be a good idea since its a 92. If you have a boost leak it shouldn't be an expensive fix.

 

there is 90000 miles on the car. so not many for a 92 at all. but yeah along with that when i put my foot into it it makes a varoooooom sound real quick then it stops its only when i put my foot into it.

 

I agree start with wires and a boost leak test, if that doesn't do it its probably a bad coil pack or MAS.

 

ok when you say a boost test i would have to take it to a shop huh? or is there something i can do at my house? also what is the best way to clean the MAF sensor cuz i bought a cleaner at karagen and it said it was good for all motors except the mitsubishi and the toyota twin turbo motors? also wouldnt the check engine light be on if the MAF sensor was bad?

 

You just have to make one which isn't hard to do then get a bike pump or compressor.

I would not spray anything in the maf, its not going to help anyway, and no the check engine light isn't always neccessarily triggered with a bad MAS

 

some one said a new fuel filter and it might have something to do with vaccum leaks when i started it up for him and we reved it he said he could hear no leaks in the turbos. ould it maybe little things like that?
