ok well i got this 91 crx dx with a d15b7 in it and i think that is the dx motor for 92-95 civic,and when just barely push on the gas it feels like its cuttin out and then my check engine light comes on only when im drivin for awhile, but when i shut the car off and turn it back on it goes away anybody know what up? and how do i check to see what code im throwin?help a brotha out thnx

 

Do you have mpfi or dpfi?

There is a light in your ecu that will blink for you to check codes. Turn the car on and count the lights.

 

i dont know?....yea that little light was just blinkin will it tell me when my car is on or do i have to turn the car off cuz if so then i cant check it?

 

see i had a ek before this crx and im still tryin to figure out everything with this obd0 **** lol

 

Turn the car on.

Wait until the light pauses.

Count each time it lights up until it pauses again.

The number of times it lights up will tell you the code number.

Search your code number.

Fix your problem.

 

my only prob is that the code only comes on when im drivin and if i shut the car off then turn the ingnition on its not there anymore

 

well i have mpfi so does that have anything to do with it?

the Check Engine Light will go off every time you shut the ignition off but the codes will still be retained in the ECU until you reset it - turn ignition on and look at the LED on top of the ECU and count the flashes - unless it has been converted to OBD1 and then you will need to jumper it

 

it blinks like every second and doesnt stop there is no slow blinks or nothin

 

Are you sure it does not pause for about 1.5-2 seconds then it blinks again.

if it is just blinking once then pausing, I think that mean 02 sensor.

Search for your pm6 codes.

 

yea im positive when i turn the key on it blinks once fast then it just sits there and blinks

 

yes, code 1 is O2 sesnsor

 

o and i just looked and my ecu and it has a stamp for 89 and mines 91 that shouldnt affect anything cuz its still a pm6 right?

 

yea but i had a 02 sensor expletive up in my coupe and the check engine light stayed on

 

some guy told me my intake mani isnt for this motor here is the pic http://i60.photobucket.com/alb...5.jpg

 

bump for help?

looks like D16A6 intake manifold to me

 

it shouldnt matter if its on the d15b7 right?

 

won't matter - looks like it also has D16A6 head and valve cover on it

 

i thought that was 88-91 si head i was thinkin of puttin a z6 vtec head on it but i need a daily driver for now i dont need to f*&k up this block

 

damn i still cant figure out why my car feels like its missing when i just touch the gas a little but when i punch it it seems ok its wierd cuz my 96civic dx with d16y7 was faster

 

Check the wiring on your o2 sensor, maybe it fried somehow.

Check the distributor cap, plug wires, and plugs. If those are good make sure your ground wires are all good.

 

ok cool yea its got a new cap new wires im gonna pull the plugs and check those and check my o2 wires and where its pluged in to see if its loose

 

everything is cool so wtf this sucks

 

Sounds like whoever did the swap didnt switch the wires on the TPS. When going DPFI to MPFI (like the swap you have), they need 2 wires need to be reversed, or else the resistance is telling the ECU your giving it full throttle at idle and idle (or close to it) at full throttle.
