hi all, ive had a good read through lots of threads about engine temp issues. and it seems the thermostat is just as common as the temp sensor. but i cant quite fiqure out what my issue is, so here goes... driving this morning, i did approx 20 miles, got home from the misses place and noticed my engine temp wasnt quite at 90. was about 86. so i decided to go back out and try and get it to 90 as ive never had this before usually up to temp within minutes. was driving like an **** at high revs and it wouldnt budge. then sat at traffic lights and it dropped to about 83 ish. then when i pulled away it rose to about the same 86-87. and thats as far as it went. do you reckon its the sensor? or thermostat? im going to take it for a blast to the jet wash later...see if it rises to full temp. im hoping it isnt the thermostat as i have read its a right pain to do, a job that involves alot of swearing and tool chucking?
