1994 Crown Vic LX spark plug wire set
Hi, I have a rough idle and plan on cleaning, replacing, checking all the parts that are the usual culprit that cause this.
I took the vehicle to a mechanic and they wanted to charge about $750 dollars to to a fuel injector clean (what that entails I don't know) replace the DPFE, plugs, wires, PCV, F.F. (don't know what F.F. is). Also they were going to clean the throttle body.
I've got a Haynes manual and this stuff looks simple. I guess my question is really about the spark plug wires. They were going to put in a $90 set. While searching for parts I found some sets that were far cheaper. Nifty colored ones too. However I'm not sure if I need 8mm or 8.5mm, and if I get the "racing" wires if I'll need to do something with the distributor cap...something about HEI.
I'm a new motorcycle rider and I've gotten my hands way dirty on my bikes, but I'm ready to get under the hood. The car drives great other than this stupid rough idle. Sometimes I feel and hear a clicking noise under the gas pedal when the car is bucking when I 1st start it. Once the few clicks go away and the ride smooths out, I'm good. At stop lights the voltage/engine will drop and rise, but I can take off smoothly once warmed up. From reading it sounds like a vacuum leak and combo of dirty throttle body, bad valves/sensors.
Here is the MSD plug wire set part # Part Number: 5008-03141664 from partsgeek.com
Also the cheap Bosch set W0133-1613330
Am I correct in that this car needs NGK TR55 plugs? Would it benefit from running hotter plugs?
I don't know if I'll need anything else besidkes plugs and one of these two sets to replace the spark part of my car. The air and fuel sensors/valves seem a lot more straightforward.
