I drive my car and all of a sudden the RPMs drop and the car stalls. I restart the car and it won't start. It will start and stall again. When I press the gas, It is chocking. I feel like the gas is not working. I put fuel injector cleaner but the problem still remains. Sometimes the check engine light goes on with a map sensor and O2 sensor code. I turn the car off for a while and then it will start up with no codes. Any advice????

 

what kind of car is it? ITR? Civic with B18C5?

Type R

 

lean out the idle to -20 or -25 , then let it sit for ac ouple of minutes to avoid puddling, then fire it up...I had the same problem. OHHHHYEAHHHH my car is out of the shop

You got rid of your GS-R?

 

do you have a VAFC installed?

 

yes he does

 

ok then, what are you doing to the MAP voltage? first check for a bad connection, then see if you are increasing fuel a lot. I've heard of cars doing this if you increase fuel even as little as +8% map voltage..

 

If you throw a MAP sensor CEL, and your MAP sensor voltages and ground seem correct, I suggest disconnecting your v-afc. I've said it many times before, the v-afc does not seem to be compatible with many type R's that tried to use it.

 

If I am not mistaken he is actually using the fields unit, not the Apexi

 

Correctamundo. I do have a Field Unit. Thanks Digital for covering me. I checked the connections b4 but I guess I got do it again.

 

I've got 60,000+ miles with the field & only 1 map sensor code - replaced the sensor & it has run fine since. However - what happens when you turn the field off (a nice advantage over the vafc!)????

Does it continue the problem?

 

I gotta try that.

 

First of all check your pump relay and ignition switch.....they go bad on hondas

 

check to see if you have any fluid dripping on the o2 sensor at the header. I had a small coolant leak at the throttle body dripping down and it shorted out the o2 sensor with the fluid making its way down the wires into the sensor. I had the same symptoms.
