Well I have a problem with the itr. Just rebuilt the motor to JDM spec and it fuel cuts or stutters at 4k rpm and over. Changed both O2 sensors, sparkplug wires, distributor ignition moduel, and external coil. I am stumped and need your help. The other night while driving after I changed all these parts the car just died and wouldn't start. Then in the morrning I went back and it started but struggled to keep running. All responses will be appreciated. Thanks

 

any cel's?

 

Check for a loose ground bolt on top of the thermostat housing. Sounds like exactly what mine did to me.

 

No cels at this time

 

check the three grounds, n make sure dizzy is all good everything in it

 

my car ended up being the cap and rotor for the dizzy

 

Put new plugs in, then swap a dizzy off another R that you know is running properly. Willing to bet my left nut the dizzy is the problem.

Also, did you do any cutting into the wireharness for anything? If so, re-check solder jobs.

 

i'd check the thermostat housing grounds for sure (this is where the ecu grounds at) also maybe the MAP and TPS sensor plugs are swapped?

 

Be sure the TPS and MAP sensor plugs aren't reversed. They're the same connector and easy to mix up. My last build did the same thing, and this was my problem.

 

Thanks for all the info. Checked the thermostat ground and its on tight. will check the tps and map plugs today

 

well the tps and the map sensor is all good. I guess gotta change the distributor. anyone have any other suggestions. anyone also looking for a msd blaster coil only in the car for 1 day when was working. also got a new distributor ignitor moduel bought from acura for $180
