I have a 1997 civic ex with a 1998 H22a4 engine, JDM H22a Tranny, P72 ECU (Jun Programmed), intake, header, exhaust, muffler, Act pressure plate, Act clutch disc, and Act flywheel along with Place Racing Motor Mounts and Axles.

First, I have a bad idle. Bobs slightly. Replaced throttle position sensor with little results. EGR valve issue or something else? Does a P72 even use an EGR?

Second, My car shakes like a beat who-re when accelerating. I emailed place racing and they told me their axles weren't gaurunteed for life which I could have sworn they were. Can I use regular civic axles? I'm not all about paying $400 every two months for axles.

Third, Timing belt seems sloppy. When in nuetral I can have a friend rev the engine and the belt slaps off stuff. The belt on my alternator wears off also.

Would it be worth it to replace my usdm head with a JDM head?

Any help would be appreciated.

 

compression test your motor and check your axles...if your timing belt is too loose you may have jumped a tooth and possibly bent some valves....

no you can not use your civic alxes, tigten up your timing belt, and no P72's do not read EGR
