QUOTE(Defgeph @ May 15, 2007 - 12:49 AM) [snapback]557731[/snapback] Update: I checked the boost gauge as suggested by Manny. It turns out the nylon line connected the the boost gauge was leaking. I always hated this nylon line. So I replaced it with a rubber hose. The vac reading is now normal on the Autometer. The Greddy on the other hand is still fluctuating. Funny huh? I did a spark plug change, Still ran alittle rough at times(idle after boosting) but doesnt stall anymore. So I think after a regap of the plugs I should be all set. I just dont get way the Greddy's vac readings are all over the place. But thanks for the help guys, it's running alittle better now. DEF good ol autometer strikes again.haha. you have to remember that the greddy is probably reading a lot more detail then the auto meter. my blitz reads .65-.70kpa depending on time of day, weather, if i have my headlights on , idle speed, etc... when you convert that over to vac, its really somewhere around 19-20vac difference. i hope you dont mean that you want to regap the plugs after you just put them in? the ground strap could break off if you regap after they have been used already. what rpm is your idle at now? -------------------- 15PSI - 30MPG - Megasquirt Tuned

I have a brand new set in the glovebox ready to go in.
My idle is @ 850 rpm. It will fluctuate alittle 700 to 1000. It will hold steady at 1000 or 850. Now its mostly 850. I notice misfire in low loads on the engine. For example cold engine very mild acceleration. It not accelerating smoothly. I think I may be gapped to wide. It's gapped at 30, I'm going down to 28. This only when its cold. After warm up it goes away. --------------------  I will return one day. |

do you have a wideband installed? that would give you a good idea as to whats going on when the car feels like it does. -------------------- 15PSI - 30MPG - Megasquirt Tuned

I have it installed. I have to check what its reading the next time I drive. I can't remember what it was reading at this time.
This started happening after the plug change. This is why I'm leaning toward the plugs. -------------------- I will return one day. |
