I recently took out my transmission and head for upgrades I put everything back together and now I Have a misfire and my boost gauge is reading only 10 to 15 hg at idle before I took it apart it was running great it is a 3 liter with all arp hardware obd1 running c2 with #30 injectors I know the spark plugs are good and gapped right and my wires are brand new can anybody point me in the right direction on how to start to diagnose and fix my problem

[TBT-Syncro]

check for vac leaks
check all grounds
make sure the ecu is seeing 12v
verify idle air/fuel
check cts

start with all the regular basics.

[redraddo92]

Grounds are good air fuel right on just put a new intercooler on didn't find any leaks in the piping but maybe I need to check again

pressurized the entire system? If the vacs low all of a sudden Id expect something to be out of place.

[redraddo92]

It was wrong from start up Im just trying to figure out why

Check your compression.

check cam timing, may be off a tooth

[redraddo92]

im going to double check the timing i thought i was dead on i triple checked it when i put the motor together i checked my compression today and it was perfect all across the board it seems to be a misfire on one cylinder just cant figure out which one its obd1

Any misfire codes? Let it idle , and pull each plug wire, the cylinder that doesnt change the misfire is the dead one. I ve seen bent valves on heads from hadling, there is always a valve open once the cams are in, and since there isnt a combustion chamber in the head...

Bent valve would show on the compression test.

correct!

[Scrubbs]

Yep, absolutly.

[redraddo92]

so i pulled the motor apart checked timing rechecked timing everything was perfect put it all back together still misfired pulled each plug wire until i found one that didn't change the noise of the engine checked the wire it was good checked the spark plug turned out to be that all that work for a bum spark plug

[Scrubbs]

You learned from it. Start your repair logic doing the easiest things first. At least you found it, i have a friend thet would still be checking wireing on the complaint.

[redraddo92]

honestly i did learn from it i learned rip things down twice check your plugs once
