heres the one I use...(ABOVE)...now ILL grant you , that you can buy a whole lot cheaper tool for checking tires, but I use mine basically for reading header temps, to detect mixture or ignition problems or missing cylinders and you may not want to spend the money,
heres a cheap one (below)

heres a far better one but still less expensive

at times they are WELL WORTH THE MONEY in lowering the time and effort required in diagnoseing problems, and yeah! you do get what you PAID FOR in the better models
the key here is knowing what your looking for in a temp range,not so much any exact tempiture, if your cars running correctly run it around the block a few times then stop, lift the hood and read each individual cylinders exhaust port or header near the cyllinder heads and take notes, later when you find the cars running rought in the future do the same thing and be aware that low temps usualy indicate missing ignition of fouled plugs or overly rich f/a ratio, hotter than average temps can usually indicate vacuum leaks, faulty injectors etc. temps generally fall in the 600f-1200 F range depending n tuning, compression, type of headers average rpms. length of run time, outside temps, etc. youll need to become familiar with your car, the key is looking for consistancy! and yes the rear and center two cylinders tend to run just a bit hotter from less airflow cooling
I use this

but you can learn a good deal with
a factory shop manual,
fuel pressure gauge,
a timing light,
V.O.M. meter,
vacuum gauge
and infrared temp gun that reads in the 800f-1600f range
along with reading sparkplugs and a fuel pressure gauge
