ok so i have an 88 ef with a 95 d16zc sohc motor in it, the ecu is a chipped p28 obd1, the motor has the obd1 map sensor on it HOWEVER, i changed the map sensor that bolts on the top of the throttle body, now the old map sensor on the firewall ( the stock ef one) i pulled the plug out of the bottom and pluged it into the obd1 map sensor, now wat do i need to do with that top plug, do i need to get a second new sensor for the top plug, do i unplug it, i left it hooked up to the sensor that has the vac lines that run into the cannister and the back of the intake manifold.



SO NOW TO MY PROBLEM........the car is idling fine, but when i give it a little bit of gas it starts to stutter, i keep giving it a lil and lil more gas and it continues to stutter until it reaches a point where it starts revvin hella high and the studder stops but theres no smooth transistion its either revin love around 2000 rpms and stuttering and then i give it a lil more gas and it switches and runs like 5000 an does stutter, i have changed most of my parts, map sensor to obd1, ive changed the main relay, im at a loss for wat is wrong with the car, any insight would be greatly appreciated? give me some tips and ill tell you if ive tried it fixed it or changed it, ive been at this for almost 2 months now and this car is way to simple to be this big a pain in the ***. PLEASE PLEASE PLEASE PLEASE HELP IM LOSING MY MIND WITH THIS PIECE

 

i had a problem similar to this in my cb7 and it turned out being bad spark plug wires...!!!

 

the plugs wires dizzy and ignitor are all new

 

then i guess thats not your problem

 

my ef is doing this as well but there is no smooth transition when your foot is on or off the gas pedal, your either going up in speed or declining in speed

 

look at my post in the civic/ del sol section someone from houston is helpin me and hes helpful

 

I'd start with the easiest solutions: cleaning the IAVC (or whatever it's called - along with other applicable sensors) with some brake cleaner and checking for all vacuum leaks.... and fixing them.

From what I read on here, and my personal experience with similar situations with my own Civics, fluctuating and/or sporadic idle will wind up being one of those two problems 8/10 times.

Give it a try.

 

thanks ill try that tomorrow

 

sounds like a TPS problem to me

 

mine did this. just unplugged it. throws a code but i'm not worried. haven't had a problem since.

 

what codes is it throwing?

id start there.

 

my friends p28 was chipped wrong and it would do the same thing
