he thought it cd have been throttle body when he pressed gas pedal and got little response... so he swapped out ecm... after reprog ...started up ..instant response on gas pedal.. took it for a quick spin and it was off like a jack rabbit...so ECM was the prob. I think the scan tool was an XTOOL.. not sure of model... but it was about a 10 inch screen.... but like i said.. hes a retired Dodge tech and has all the good equipment.

hey... my tech friend found the prob...faulty ECM/PCM... Swapped it for one he had with him... reprogrammed it.. car ran great...just have to get a new/recon unit... so after changing all timing chains, sensors, plugs n coils... it turns out its the ECM... ah well... at least it got the timing chain done.. 167,000kms... Thank you so much for all your input and insights.

my tech friend is on his way over... hes a qualified Dodge tech..retired... will keep you updated with what he finds....thanks

hi.... question for ya.. what if i change the 02 sensors and put a new CAT on ..., do you think that cd help...also i took these readings off data stream on my obd2 ... i have no idea what they mean ..any insight wd be appreciated.

the tech who is coming out is a ex Dodge certified tech.retired.. i know him personally... he knows his s##t....lol

had them changed just under 12 months ago....why that question ?

thanks for the insight...i will ask tech to check the power at ecm b4 we swap it out.... cd save me a bit of cash....lol already got the PIN from dealer just in case.

ntk sensor... changed out the knock sensor... took for test drive... ran great for 200yds.. then started to stall out... p0300 still showing... think it might be ECM....i have tried everything else... research shows ecm cd possibly cause same symptoms ... have a friend coming round with a recon ecm... just have to get PIN from dealership to reprogramme ecm....hope that fixes it..cos im getting ready to smash the damn car with the biggest hammer i can find......lol

hi guys... managed to take car for test drive...after a few hundred yds started bucking and about to stall out... hooked up OBD2 and found p0325 ..knock sensor... gonna change that later... hopefully solves prob p0300 code. If not.. will do comp test.. leakdown test.. maybe remove 02 sensor to check if runs better... uf it does i think i will have to change the CAT... what do you think ?

hi... thanks for the input.. had car for 10 yrs... only 161,000 km (100,00 miles) im in Canada.... on clock.. wifes daily driver.. regular oil change every 5000k (she always gets it done ). Found dirty throttle body, also air intake gasket wasnt in best condition....cleaned and replaced both gaskets.... checked fuel pressure (58psi). Where can i get my hands on a bi-directional scanner...to do relearn on sensors ..?

Hi... new to forum. I am at my wits end... P0300 code wont go away on my 2010 Journey 2.4L DOHC VVT.. changed timing chains, tensioners, crankshaft sensor, MAP sensor, IAT sensor, coilpacks and plugs...tested cam sensors( both operating as they should), still cany figure out what the hell is causing the Random Multiple Misfires.... Can anyone help with suggestions as to what i can do next...? ( local shop quoted up to $4k to diagnose and repair ). Thanks.
