I've got a 2000 USDM Integra TypeR(stock). I red-lined 3rd into 2nd(assisted by a few distractions)

I've replaced the timing belt,distibutor cap,rotor button,NGKplugs&wires&pcv valve. Also im about to replace the valve cover gasket & fuel filter.
I'm recieving codes; (PO302) Cyl. 2 Misfire, (P0304) Cyl. 4 Misfire, (P0300) Random/Multiple Cyl. Misfire Detected, (P1399) Manfacurer Control Ignition System Or Misfire.
With the stuff i've already done, i've got alot of improvement.The engine seems to be running strong only that the valves are louder than normal.If i drive it, as soon as I let off the gas it dies,without driving it; in idle it stays running but at around (4-500) RPM.
Any help would be very much appriciated.

 

What kind of valves do you think would be best to go with? OEM or ..........
Im not sure of whether or not i want go performance or not.everything else is stock as of now(except the after market parts listed above).

 

anyone know who manufacerd the OEM valve for 2000 ITR

 

Wait, you downshifted from 3rd to second and mechanically overreved the engine?

Sounds like time to take off the head and have a look, you probably bent a few valves. Replace with OEM parts.

 

yes that is what happened

 

i have code p1399 and dont know what can it be, the only thing i can think of is the fuel pressure regulator i replaced it with an after market does any one know the correct pressure seting

 

About 43psi.

 

What Kai stated, you definitely have bent valves in cylinder 2 and 4. No compresson, no explosion so the CKP sees a misfire. Codes (P0300) , (P1399) tie with the misfires in cylinders 2 and 4. Do a compression check, you will likely have little or no compression in 2 and 4. Good luck.
