cheap300

1998 GS 300 155km. Car was running like crap and pulled the codes. Miss fire on #5, changed the coil, put it back together everything was fine. Next day does the same thing, pull codes and now its #2. We pull it apart and find some coolant in the vally. We dry everything up and it runs great for a week. Now it feels like a quick miss, if you have ever had a manual car and you can some times feel the a/c compressor kick on. Its not bad nor do I have any CEL, but its getting on my last nerve. When we changed the coil we also did all plugs and wires. All parts from lexus, don't know what to do now. I also did a timing belt all oil seals in front of motor plus a new vvit pully about a month ago. Everything is dry in the valley and the timing is right. What else can I look for? Sorry so long but its getting on my nerves. THANKS.

Do a block test. You migh have a blown head gasket. Check the plugs to see if there clean. Coolent might be washing he plugs causing a misfire and bad coils.
