SOURCE: High compression in 1 cylinder of a 170 ci. 40 psi high.
Hi!
Per the Ford manual, the acceptable range is 155-195 PSI. It sounds to me like you don't have a compression issue with this engine (without knowing the exact readings for each cylinder). Normally one cylinder being higher than the others, but still within spec, would not concern me a lot. Had one been much lower, then I think that might be cause for concern. There could be many reasons for the one hole being higher. If the engine hasn't been rebuilt in a long time, there could be carbon deposits in the compression chamber. There are many chemical fixes for this availble at your local parts store. If the engine is running fine with no pinging or detonation, I'd just continue to enjoy your classic ride (I own a 1971 Challenger converitble with a 440-6 pack, so I understand the joy of a classic car!).
Good luck and please let me know if this helps!

SOURCE: no compression in one cylinder
Timing belt slipped around cam pulley. Take off your timing belt cover and check the position. This would explain misfiring and compression loss. Stretched belt or missing cogs in belt likely culprit.
SOURCE: what is the cylinder compression psi fpr the 2.0 liter engine
usual on 4 cylinder around 175psi.225psi is very high for your car,150psi seems ok,you may have two problems.A leaking head gasket and high compression due to carbon build up on the pistons.Check your Hyundai Dealer to see is this problem is covered under their 100,000 mile warranty,it should be.IF not then
the head needs to come off and had gasket replaced along with clean the top of pistons since they are right there,sounds like and easy fix.also check condition of radiator,and I would rec. replacing thermostat since some Hyundai models had problems with their thermostats
SOURCE: cylinder 2 misfire, replace both coils, spark
check your computer next or look to see if you put the position sensor 180degrees out
SOURCE: how much will it cost to fix cylinder 2 misfire?
i don't know how match the cost, but it will he you, first change the position of the ignition coil to another coil also the spark plug, read the misfire code is it P032 or replace the code, if on cylinder 2 again appear the misfire check the compression, if ok go to electrical and check wires go and from to cylinder two coil to pcm, check the ground on #2 coil, if all this ok, see the difference reading by multi tester to coil reference if all good, reprogram your pcm, or replace if necessary
