Intermittent Bogging

Intermittent Bogging
First off some specs. Stock Y8 Block and Head with a 54 trim t3/t4 running crome using jd's y8 maps for timing. Car runs great some of the times. Other times it is a bitch and runs real real rich and misses. I dont think its a spark plug issue. Ive changed them a million times, with both bkr7e and bkr6e gapped between .028 and .032. I dont notice a trend between when it runs well and when it doesnt, except that maybe it runs worse at night, altho that could be total bullshit.
Any ideas on what could be causing it?

Re: Intermittent Bogging
when you say all rich, do you mean like your WB pegs competely rich for the entire run time? or for only a moment?
How long is intermittent?
Have you messed with the MAP sensor wiring? Loose/shitty wiring (if its the right one), will cause the ECU to see max MAP reading sporadically.
Thats my Ediagnosing shot in the dark hahah.
Need more info. ----, a Dlog of it occuring would be primo box.

Re: Intermittent Bogging
ill try to get a log of it tomorrow. For example, I could drive to work (~10 miles) and itll be fine, but on the ride home itll be a bitch. Rich as in about 10 AFR. Right now i'm using a stock map sensor with a molex computer connector hooked up to it..i have also ran a moto 2.5 sensor. I'll try the moto out again to be sure
