Hey - two truths with a car. Only thing that fires the fuel (gasoline engines) is the spark plug and only things that touch the road are the tires and nothing else much matter if those two items aren't good they are the weak link. With plugs it comes right down to how lousy some are even packaged for handling before you get them, proper resistance, metal and porcelain issues and how made, one unit of metal or crimped together junk. Just plain rust resistance of the metal wrecks the whole show later if not changed Spring and Fall like wicked old days. This car calls for Delco for a reason so even if not the total issue right now it sure could be. Sample pic of poor quality if it shows.............. ^^ Pic was there if it disappears I can't help that, T Hammer Time Ultimate Carjunky / Moderator Oct 19, 2014, 7:43 AM Post #27 of 29 (1073 views) Re: 1990 cadillac deville 4.5 multiport has a miss Sign In Quote i like delco to but they are way over priced. ive used champions in everything ive ever had for the last 20 years That is a mistake. Every manufacturer engineers their engine to run better on a specific plug. That would be Delco for all GM products, Motorcraft for all ford Products and Champion for Chrysler products. Most Asian vehicles run better on NGK. These are known facts. It DOES matter. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional. cdwdaddy7 User Oct 22, 2014, 5:28 PM Post #28 of 29 (1055 views) Re: 1990 cadillac deville 4.5 multiport has a miss Sign In well i got it back up and running today. running much stronger but still has the slight shudder when you are driving and giving it just the right amount of gas. its not a tranny problem at all. when i run the on board it gives no e codes but does give a lot of different p codes. where can i get a list of the codes and how can i clear the p codes? certain that most of them are from it being torn apart and starting up a little rough. could it have anything to do the catylitic conveter or the smog pump? ricksbike New User Nov 6, 2014, 10:09 PM Post #29 of 29 (1039 views) Re: 1990 cadillac deville 4.5 multiport has a miss Sign In I agree with Tom,never-ever use anything but AC Delco plugs, for some reason all the rest misfire,tried everything,every brand all misfired,I was a cadillac tech for 10 years,did mostly drivability and electrical work. 1 2  View All Email This Post   Automotive Repair     Auto Body Repair and Refinishing     Heating or AC Issues     Electrical and Wiring     Brake Systems     Car Stereo Repair Advice     General Discussions     Car Making Funny Noises     Engine Fault Codes     Engine Troubles     Exhaust Systems     Steering and Suspension     Transmission Troubles     Tricks of the Trade Automotive World     General Discussions     Antique Car Talk     Car Shows and Events     The Bargin Bin     Motor Vehicle Inspection     Car Care Tips     Traffic Tickets     Gasoline, Motor Oils, Concept Cars and Engines     Auto Insurance, Financing, Leases, Warranties Truck Repair     General Discussions     Truck Engine Repair     Truck Suspension Repair Motorcycle Repair     General Discussions     Motorcycle Engine Repair CarJunky     Open Posting     Board FAQ's     New Board Suggestions
