95 civic ex d16z6..replaced old d16z6 with another and this happened .low low idle low pressure at the tip of exhaust...redline just over 6grand???didnt pass smog and i feel like engine isnt as strong...

 

any CEL

 

no cel.. ive been readin and it seems like a popular problem

 

Does the CEL work?

Clogged cat?

Last ignition system tune up?

Clogged fuel filter/low fuel pressure?

Popular or common problem?

 

yes light works cat passed smog so doubtfull just tuned up when engine was replaced,

 

If the cat is fine, then please try to explain the low exhaust pressure.

Ignition/mechanical timing?

Fuel pressure?

What did your tune up consist of?

 

water pump timing belt plugs wires...filter and dizzy were said to be fine

 

Inspect the cap and rotor yourself and either replace the fuel filter or check the fuel pressure.

Timing?

Low exhaust flow?

 

oil n and oil 00filterwere done as well

 

timing was just checked..im far from a mechanic so i couldnt tell you if it was correct

 

If you assume everything is fine without actually knowing, then you'll likely struggle to make any progress in solving the problem.

 

ok well would i don't assume my mechanic is stupid.

 

I don't know your mechanic. I just know that it's not uncommon for mechanics to get it wrong. And if you have complete trust in your mechanic and wish not to question his diagnostic skills, then get your car to him ASAP.

It just seems that you already know what the solution is and is not. In this case, a tech forum like this can't convince you to think otherwise. Pay your mechanic to fix your car.

 

i dont have to pay him... and i came here for advice from others who shared the problem, i dont know what is causing this problem,,if i did i wouldnt have posted.....

 

You say you want advice but you reject suggestions and make huge assumptions. Nobody can tell you what the problem is unless you start checking things suggested to you. Otherwise, you are asking people to guess based on symptoms that can have many different causes.

If you can't or won't inspect things or do some tests, then you really should just pay your mechanic.
