misfire? lemp mode? help please?!
Ok so this problem has me screaming for help. installed screamin deamon coil and Kingsborn wires months ago with my 17%pulley and brisk colder plugs. car ran great for a good month then when id hammer the gas it would go into lemp mode. No CEL hard to crank back up but all was normal as long as i didn't hammer it. Then it started dying when hammered. Iv replaced the throttle body, bypass valve, spark plugs again, Then it started idling rought and i have to rev it higher than normal and ride the clutch to take off and if i hammer it, it looses all power and throws p2301 and p2304 codes. A shop looked at it briefly before it started throwing codes and said my 4th cylinder fuel injector was stuck open so i replaced it. please help :(

Using high octane fuel right?
High octane is even more important with a pulley... Next....just for giggles, toss your old coil on...see if all is good....if you still have an issue.. Might be worth moving the fuel injectors around....see if the misfire follows the moved injector.... A compression check might be a good idea.....it is possible you have low compression... That would require a mechanical fix...often a valve issue.... Good luck. |
P.S.
It is LIMP mode.... |
Old coil was junk. And compression is all good. i only run the highest octane fuel in it. buy all my gas at same place every fill up

A bit of a long shot....
but a few folks found regapping the plugs to slightly wider helped with the extra voltage if the scremon-deamon coil.... Just a word of warning.... Brisk (owned by champion pretty sure)plugs were all the rage for a bit..but folks found they had a VERY short life....sometimes 3000-5000 miles....NGK plugs tend to go 30,000-100,000 miles depending on id just a S or pulleyed/JCW car.... Maybe try a different gas station...you never know who to trust..station owner might be ok, but a supplier could be selling him crap product.... |
