Spark knock and low intergrator and blm

[montessgtp]

I noticed latelly that my car has lost power. I put it on the scanner today and noticed im gettin knock retard above like 2500 rpms like up to 12 degree's. Also my intergrator and blm are low. M intergrator... was around 128- down to 124. my blm dropped to like 112 during normal driving. Can these to be related. I keep gettin a code for MAP sensor..but its a brand new map sensor. ANY INFO would be greatly appreciated. BTW Its 1992 Grand Prix GTP 3.4 DOHC

RE: Spark knock and low intergrator and blm

Check the wiring for the MAP, mostly the 5 volt reference. It probably ties into something else though I dunno for sure, maybe TPS? Anyway, the INT is fine, the blm is low though. Check your fuel pressure...though I suspect the MAP or a related MAP issue is your real issue.

What scanner are you using? Can you send me a datalog?

I have a Snap MT2500... or i can use freescan with my laptop... i think i can log a over view with free scan... ill try tonite.. as for my MAP sensor the clip is broken n i think it keeps coming loose ive yet to find one in the junk yard i can just slice in its place. However, even with it plugged in correctly and with no SES my knock retard is still at higher RPMS...Would a lean condition cause my car to ping intially cutting back on spark? I believe when the car bLM go bellow 128 its adding fuel? Correct me if im wrong.

no, its cutting fuel if it goes below 128. Someone online was saying that 97 injectors are higher output than 91-95 but I dunno for sure. Could be it. Send me a freescan file of it idling, cruising, and then WOT.
