if you tighten them to tight then you will end up with a no start and no compression .just like these guy’s http://youtu.be/HWnMxJp97-o

ok i listen to each injector and they all sound ok . the high as the feul presure got was around 50 to 55 psi at wot. i took the line off the difram going to the intake i smelled a little bit of gas but did not see any . also this morning i noticed that my rpms when at cold idle is no longer staying at 1,500 rpms tell warm like it used to. when warm it idles at 750 rpms .

[quote=”ToyotaKarl” post=72059][quote=”Accord” post=72052]i just pulled the exhaust off all it did was make the car louder still the same issue .
could this be the feul diaphragm at the end of the injectors going bad ?edit: i just remember my exhaust has a big leak in the flex pipe .[/quote]
I think you are referring to the fuel pressure regulator. At WOT, the fuel pressure should increase. You can inspect them to see if it has a bad diaphragm by removing the vacuum line to it and see if fuel is getting into the vacuum line…. Another thing would be to keep the fuel pressure gauge hooked up to the car and see what the fuel pressure is at WOT and when you are having this issue.
Another thing…You can have proper fuel pressure, but not proper volume… Check your fuel lines for bends/kinks as well… Also, you may be having a fuel injector issue.
Also, the exhaust leak is something you should fix for several reasons…..

i will try the fuel gauge at wot today and stick a screw driver to each injector and listen to them at different rpm’s .[quote=”college man” post=72058]If you have a major exhaust leak before the o2 sensor
its affecting performance. do you smell fuel?[/quote] this year of accord has the o2 sensor in the exhaust manifold before both parts meat up . but can to much exhaust flow hurt performance in a stock engine ? the weird part is it passed smog like this with flying color’s .[quote=”ToyotaKarl” post=72059][quote=”Accord” post=72052]i just pulled the exhaust off all it did was make the car louder still the same issue .

http://www.ericthecarguy.com/faq/solving-automotive-performance-issues%5B/quote%5Di looked at this video befor posting and every thing checked out ok.
[quote=”ToyotaKarl” post=72024]Are you having problems getting the RPMs to increase when it is in neutral? It could possibly be a clogged catalytic converter (or a restriction in the exhaust system somewhere). A quick test if you don’t have a vacuum gauge is to disconnect the exhaust temporarily and see how it runs….
Eric also has a video…
If it only has issues when driving, there could be a driveline issue…

look for bad ground’s as Honda / Acura are know that when they have a bad , dirty or loose ground to do crazy thing’s . also look for short’s and broken connecter’s .
