Quote, originally posted by whitevibe04 »Any body has this problem I have to drive around 3 to 4 miles before my engine temperature gage is showing that it is operating at the normal engine temp?Anyway I just changed my spark plugs at 40k with NGK BKR5E1X-11 P/N 5464. The ones that came out where the factory NGK 1FR5A11 are they different heat ranges?Now the car engine temp gage show that it reaches normal engine temp after driving less then 1 mile, the outside temp does not matter is probably around 80 degrees here.Or did I hit some thing when changing the spark plug? Any one knows where the engine temp sensor it located?You tell us, if the plugs you bought are of a different heat range... you bought'em...lol Did you just grab a set off the shelf and say "oh, these look like they'll fit" ?? As far as the motor warming quicker, that's a strange one, i can't imagine plugs changing anything, i mean fire is fire... As stated above, you could be burning fuel better based on having new plugs, but figureing out weather or not you have the proper heat range is criticle....I just crossed the PN at NGK to these
http://www.ngksparkplugs.com/p...x.aspSo you replaced them with Iridum plugs... what did you spend on them? Should be ok, i'm not a fan of iridum, i like the regular old coppers myself (v-power in NGK)The engine temp sensor would be screwed into the block somewhere, so who knows, you could have bumped a connection and made it better, that's all i can think of...
