Im getting ready to go out to sea for a few days so ill ready any answers when i return so if you can please help.
First of all i installed the C.O.P. Plugs on my car. They seemed to run fine at first until after about 15 miles on them Then at half or full throttle They now cause a heavy hesitation/miss. I thought maybe it was a fuel problem so i put in the walbro fuel pump with the 12v mod and changed the fuel filter. Still does it. So then i changed the injectors to 550's and installes the lexus maf. Still the same problem but also now that i installed the injectors and Maf the car seems to lope a little at idles sometimes. Sometimes it even stalls when i let off the gas. I look around all connections are on, bolts seem tight, Hoses seems fine. I did a resistance check on the coils and thats fine and also followed the tsrm and i get 12 volts at the coil also. The wores are getting about 3 ohms of resistance. Does that seem to low and could this be the problem. Again it drives fine and normal conditions but it as soon as i try to get on it at all it hesitates and misses. I havent changed my boost at all from where i had it before the mods. I also checked the gaps on the plugs and i have them set at .020? at least i think thats what it was. The book says to put it at 21 so i went one smaller in case the spark was getting blown out? PLease help? any suggestion. I did a search but could find anything that i hadnt alrwady explained i checked and tried?
