ok I have been lookin for it but cant find it, NE ways I am lookin if some one has a pic or something to show me where all the block off plates go. And if it will help with my 3800 rpm hesitation. I still did not get how to fix it. Please someone help me.

 

Nothing you remove is going to cure the 3800rpm hesitation. It's usually caused by poor (loose/dirty/broken) electrical grounds. Read this follow the advice given.

Block-off plates replace part's on the intake manifold you've removed. If you don't even know what those parts are, you don't need block-off plates...

 

Ok I did find all the grounds and reground them and it still is doin the same thing. I hit it and kills at 3800, is there something else it could be.

 

You said it was a hesitation at 3800rpm. Are you now saying it won't rev over 3800rpm at all? That's a totally different problem with a totally different cause.

If that is the case, read post #15 in this thread.

Read the thread noted by NZCONVERTIBLE (personally I REALLY like one of the other responses that mentioned pouring cooking oil or some such thing in the gas tank) but let us as you to go drive your car. A fun thing to do.

Drive on the hwy. Drive with a light foot on the pedal in forth gear. Start out well below 3000 rpm. Take the car up to five grand in fourth gear using very light pedal and taking your time.

Can you get to five grand and over without the car dieing/hesitating/bucking? Can't help unless an answer is given.

I'm NOT interested in pedal to the floor stuff right now. Very light pedal in fourth gear up to five grand plus.

 

Thats funny I just read this last night and I kind of got it. Ok when im in no gear I can rev it to 3800 and thats it, it will some times it will go past. Then when I go to drive it will go to 3800 then bog out, But if I lightly give it gas it well go all the way to redline. I will try what you guys say but it do's not matter what gear im in, I push no go, I give it lil gas and it go's. I just want the prob to go away it is killin me.

 

If you keep the load very low you can rev well past 3800rpm on just the primary injectors. But if you go past a certain load point the ECU will bring on the secondary injectors any time you're over 3800rpm. So if you can't rev past 3800rpm under load then one or both of your secondaries are not firing. That's why you need to perform the checks I said in the thread I linked.
