ok im having some lean issues with my 95 integra LS turbo...my setup is a t3/t4 garret turbo, 2.5 IC piping, DSM BOV, walbro 255, FULL 3inch dumped, 12:1 FMU, missing link...ok my problem is that when im crusiing my a/f guage shows green but when i drop it down to 3rd to stab on it it stays green till boost then leans out and starts back firing..like if u half throttle it itll pull hard..but if u WOT it it leans out..i have a CEL on but cant get anyone around here to check it due to it bein a 95...i've been thinking maybe my MAP sensor is goin bad..maybe TPS..or may have a fouled injector?? somethin to do with fuel..anyone have any suggestions or ever had this problem and fixed it? besides get it tuned which will be done once i get alil more money

Get rid of that FMU. Are you running upgraded injectors??

BoostedEJ1

no..stock injectors

for some reason when i was using my fmu setup i was going threw maps like it was my job how much boost that 12.1 prolly isnt enough get some injectors and a basemap w/ chipped ecu. Dont keep beating the ---- out of if your gunna blow it also do you have a missinglink.

yea im runnin a missing link...what was it doing when ur MAP sensor went out?? lean out? oh i dont beat up on it..if it leans out i drop RPM like theres no 2morrow...and they dont make a conversion harness for the 95 integras?? only ones i found were to convert to obd2a or B

your 95 teg should be obd1 unless you have one of them hybrid obd2 1,s my car really would just stall or in the middle of a pull would lean out some times i would just keep getting map codes look on your pass side jump the harness to check the flash codes paste this in you browser they show how to do it and codes are also listed on there site

i already did that..it wont blink..my car is obd2 b/c i have only one dizzy plug..and another thing wierd is if i start my car and let it sit for acouple of minutes the CEL will start blinking..

well checked my MAP sensor and when i went to touch the missing link it moved..and then noticed one of my screws were stripped..so im thinkin maybe that was my problem..may have a buddy who has one so maybe i can get it try it and maybe fix my problem..if not..im just gonna get it tuned

BoostedEJ1

ok got my code figured out..and its the primary o2 sensor..so could that be my problem?? and a new o2 would fix my lean issue?

probly not i think with an 02 out your car should run richer than normal
