Is my 86 NA suffering from low "T" ?

Lots of raw fuel...acting like shes too pooped to pop..

Checked spark today both at the coil and at #1 plug both are pathetic

Question #1 How long do coils last?, If I want to put in a badass coil, which one fits in the spot?

Q2: I have inconsistent readings from the ignition amplifier which one do you guys replace it with?

Thanks for your time, shes my daily driver and chugging like a p.o.s. Honda...

Sounds like a CHTS or MAF problem. Have you checked the ecu codes?

Z31 coils are solid state. Unless you intentionally use it incorrectly, it shouldn't ever "wear out".

Check ecu codes.

Codes are 12, 13 ,31 NismoPick think you got this one 12 is MAF gonna re-check it, ordered and received the CHTS ($12) was gonna change it anyway (13)... 31 is a variety, there is no R12 in the A/C and rear defogger is disconnected after I had the windows tinted so more to follow...

Thanks... Shogunb
