Hey guys, new Jeeper here.
I have a 2000 Jeep Cherokee sport that I traded my Subaru for back in November. I'm kind of regretting it now though :X
Everything was fairly ok until recently when I added an AEM air intake. Now I get a solid and blinking check engine light, stutter, rough cruising, no power. Prior to this I'd get a small stutter occasionally on the freeway.
Anyway the code is reading misfire on cylinder 5. P0305 I believe.
Since getting it I've put on in the last 5 months:
-Champion double platinum plugs
-Rock auto coil pack
-Mopar crank position sensor(after cel)
-Ford XRE-something 4 hole injectors
-Mopar cam sensor (after cel)
-Serp belt
-Flowmaster muffler/magnaflow cat (put on after cel)
-Both o2 sensors NGK (Federal emissions)
-AEM air intake (major problems after this)
Previous Owner said he replaced the TPS and Battery(cheapo Walmart one)
Engine grounds look ok, battery leads cleaned (replacing in future)
Reseated coil pack and cleaned plugs. (Swapped the one for cylinder 5 also)
That pretty much covers ignition system, correct? I might be missing something...
I know people are going to chime in and say take off the intake, which I would/will....but there's still an underlying issue somewhere without it.
In the stock form, it did stutter occasionally on the free way (or when it was warmed up for a decent amount of time, no CEL though) this is both with and with out those new parts.
I'm currently thinking it's my fuel pump not delivering the PSI the truck wants since I about doubled the air flow going in and out essentially. Or maybe a bad valve?
I'm going to test fuel pressure today and double check it.
I have a bored out throttle body coming tomorrow also. (Not that I'll be able to enjoy it)
Hopefully someone can chime in something I might've missed. Thanks for any and all help...
