Jon, I'm john Hervey here in Forney, Texas 20 mi east of Dallas. Yes the cat if stopped up will hinder performance but I feel that the injectors need to be cleaned or replaced first. I have more people that have performance problems due to bad injectors. By the way, welcome to the DeLorean community. John . -----Original Message----- From: dmcnews@xxxxxxxxxxxxxxx [mailto:dmcnews@xxxxxxxxxxxxxxx] On Behalf Of JonL Sent: Tuesday, November 03, 2009 8:08 PM To: dmcnews@xxxxxxxxxxxxxxx Subject: [DML] Catalytic converter Howdy I'm Jon and new to the list. I recently purchased my first delorean, it's a 1982 with fuel door. My question is the engine runs real bad when cold, and runs a bit better when warm. I am familiar with Bosch early fuel injection as I have restored my far share of VDubs. The question I have is do the catalytic converters in the DMC 12 have a history of colapsing or cloging? It seems to me the engine is being very sluggish. and not very responsive to engine throtle. Could this be due to the converter or does anyone have another answer like injectors, timing, etc. Any help would be greatly appreciated. Thanks By the way I live in Texas ------------------------------------ To address comments privately to the moderating team, please address: moderators@xxxxxxxxxxx For more info on the list, tech articles, cars for sale see www.dmcnews.com To search the archives or view files, log in at http://groups.yahoo.com/group/dmcnewsYahoo!
