The only codes that come up are for misfires on 6 and 7. The head gasket was replaced just about a month ago and the spark plugs are new and do look black from firing. Sparks are dry in all cylinders and coils are good. Hoping it isnt bad compression rings on 6 and 7 or the wiring hardness...

I replaced all 8 of the fuel injectors and now it seems to idle even worst and has lots of white smoke exhaust, thought at first it as just fuel burning out, but still smokes after a long drive. thinking it is getting too much fuel now or that the oxygen sensors(s) are bad. possibly the...

Thanks, No other codes. the plugs are brand new and dot recall the brand, but don't recall the brand. but they were compatible for Jeep. As far the coils switch goes, tried that and the same misfires on 6 and 7, So I'm leaning towards dirty fuel injectors since the intake and exhaust valves...

Update, vehicle is back together starts fine, but idles rough with a little shaking, hiccup like when idling and at some speeds feels rough. Believe its clogged,dirty fuel injectors. Scan readers reads P0307 and P0306. Shop says that cylinder 6 misfires and 7 is intermittently misfiring. Going...

Now after a long process the values and camshaft has been replaced and new head gaskets on both sides. its been re-timed and put back together and now runs fine except that it sometimes stalls at stops and also coughs/chokes like at 55mph seems ok at higher speeds. Anyone has any idea what...

Thanks for the reply. I gotten a cam and now wondering about if both cylinder heads were shaved correctly. rightside (passenger) was shaved 12 thousand and the left side (driver) 6 thousand. the right side was warped from over heating more so than the right. but should both sides be shaved...

ok, Sorry for the long delay in responding back. Took the vehicle into the shop and it was diagnosed and no codes came up. Shop did say that the left side (driver side) had little to no compression ands says it needs a new camshaft as the left side is slightly bent, new valves #4 is damaged...

I redone the timeing got all the marks where there suppose to be also the links on the chain. But know it wont even start turns over but no start. Also when reconnecting the battery if i connect the ground first then the positive i get a spark does that mean there is a ground some were or a hot...

Yes, also was diagnostic done at the Jeep dealer. The #6 fuse is the small yellow one in the fuse box under the hood. I will check all the ground wires for any kinks and possibly any contact on them that shouldnt be. Thanks.

The only code that shown is P0354 for cylinder #4, possibly a wiring issue with that or a bad coil. Also the fuse #6 keeps blowing so might be a short someplace and will be checking all the grounds connections as well now. Would timing issues cause the fuse to blow ?

Thanks JPNinPA, The spark plgs are new and checked all wire connections to them and to the PCM. My brother and I are thinking the Timing Chain is set incorrectly and needs reset of which is being done now. hopefully this was what was causing these misfires to the cylinders and not giving it...

Its a 2004 Grd Cherokee V8 4.7L It now stats , but idles really rough an wants to die sometimes. also if tried driving it doesn't have much power and barely moves. codes that come up are for misfires of the cylinders and the are random at times. thinking it is a timing chain issue so having...

The battery was taken out and disconnected for about 3 weeks while the head cylinders were being worked on. Whats the possibility of it being an issue with the PCM and that just needs reflashed ? Checked all the wires, connnections and fuel pressure is fine. Starts, but dies shortly...

It started now, but dies. Getting 4 error codes of P0353, P0354, P0355 and P0358. All ignition coils issues. Highly doubt that they all went bad at once so im thinking a bad connection or fuel pressure issue is causing these codes to come on. Just put back on the heads cylinders and...
