so i got a 94 integra 4dr with a gsr swap now i pulled the head because lack of compression and got it rebuilt. know i got it running but it seems like its being held back.i just lost to a 06 scion xb when i get on it the check engine light comes on and it will throw codes 6,7,10,21 but i shut it off and the light wont come back on till i beat on it again.im thinkin ect sensor could be hurting performance if thats not good.both torque mounts are ripped so im thinkin during hard shifts or vtec engagement the motors movin alot and maybe pulling some plugs a way a little bit. if anyones heard or seen any kind of problem like this input would be much appreciated.oh and the gauge cluster lights dim at idle on and off but those only(dont think its the alt) is that a common prob on these things first teggy.

 

Codes 6,7,10,21

Did you look up and fix the codes?

 

I know Wat the codes are but I have vtec it only happens at wot it will come on an
d be off when I start the car again I know a 4 Dr gsr isn't gona be the fastest but def faster than a stock xb I'm gona time it with a timing light today maybe ignition timings off but anybody ever have codes pop up during wot around 5500 rpms or could it have something to do with not having the gsr manifold on it

 

6 ECT Sensor (Engine Coolant Temperature)
defective circuit or unplugged / defective sensor

7 TP Sensor (Throttle Position)
defective circuit or unplugged / defective sensor

10 IAT Sensor (Intake Air Temperature)
defective circuit or unplugged / defective sensor

21* VTEC Solenoid Valve
defective circuit or unplugged / defective solenoid valve
* not a valid code if car does not have a VTEC engine
** not with V-6 engine

Check to make sure you don't have the MAP and TPS backwards.

 

I would think if the map and tps were mixed up they would both throw codes at all times

 

And the car would run like complete poo. I would start off by checking the wiring harness. Its a little weird that it only happens at wot and around 5500. Does your vtec kick in at 4800 or 5500, do you know what ecu you are running.

 

Its a p72 and it kicks in at 4800 I timed it with the light and it runs a lot better but the light still comes on and I'm pretty sure my alternator is goin out to with the flickering lights at idle could that have somthin to do with it cutting out at that rpm maybe and trippin the light
