The ISCV ticking is normal. The thing is, it should idle with just the ISCV supplying the air flow...the TB screw *should* be closed. Pull the PCV hose from the TB and blow air through it toward the TB...it should be clear per this pic...

Ok...so, the coolant is warming up....that's not it. It does sound like your coil is bad. Have you set timing per the TSRM? The idle concerns me...the ISCV controls idle on this motor, that's why the screw should be all the way closed. You might want to pull the ISCV and clean...

Does your ISCV open when you shut the motor down? What does "Temp sensor is at .347" mean?

Pull the EFI fuse for a minute and turn the screw all the way in. Give it another start. The ISCV and PCV lines should be clear...blocking both off should kill the motor. What does your coolant temp gauge read after warm-up? Do you have the EGR installed (I assume you do)...what was the...

Yes, that primary coil resistance is way high...the secondary is pushing the top limit. Is there a coolant thermostat installed? What temp rating is it?

Just so you see where I'm going...High CO and high HC are not normally related. In this case, a rich misfire can cause both high HC and high CO readings though. High CO= Rich condition, CO is partially burned fuel Causes -High fuel pressure -Leaky injectors -fualty temp sensor...

The early TBs usually have that screw...and, it's usually been messed with. Later model TBs did away with it. I assumed yours would because you have an '87...if it's not there, that's actually a good thing. Yes, I know what the TSRM says on the spark test and it appears yours is...

GumOut Regane is one of the few effective injector cleaners out there...Chevron Techron Concentrate is another...they both contain polyether amine (PEA) in a concentration that actually does some good. Red Line SI-1 has PEA in it as well. TB = Throttle Body. If your idle is surging, you...

Ahhh...missed you were running speed density. I do know the MAFT Pro emulates the AFM signal for speed density, but I don't know what effect it has on fuel cut. In any case, a boost leak will cause problems...worth checking. The code 34 may be a left over...have you reset the ECU to clear old...

Check the air adjustment screw on the top of the TB...it should be screwed completely closed. Might want to replace your plug wires. The exhaust smells like rotten eggs? That's a bad CAT ;) You will have to replace it. Go to PepBoys and get a bottle of GumOut Regane (clear bottle, gold...

Did you check for codes? Check the cold start injector to make sure it is not stuck open. High HC & CO mean unburned fuel/incomplete combustion. - What did you gap the plugs at? - Did you check the plug wires? - Is there any kind of misfire? Any exhaust leaks pre O2 sensor? The...

Code14 - Check the wiring from the ignitor to the coils and the coils themself. You might want to ensure the ignitor is properly grounded per this thread: http://www.supramania.com/forums/showthread.php?t=52217 Code 34 - Very likely due to a boost leak. Check your IC piping/connectors from...

Mark the wires...you might want to sell it at some point ;)

It's very smooth ;) Gaboon - What I should have said earlier is a CBN cutter at the correct RPM/feed speed (vs "run at a slow speed") will produce a very fine finish. The RPM/feed speed is determined by what material you are cutting.

Since it's connected to the SPD pin-out, it's highly likely it's both. The HKS FCD only requires and in/out from the AFM, RPM, and gnd/pwr. Having the SLD part of the device wired in is not going to change much (if anything) on a USDM ECU...the original owner probably got it for use as a...

Interesting...a combo FCD and speed limit defender. The FCD is fairly common in the US...the SLD is not. It's only used on JDM ECUs to eleminate the speed limit built in that ECU. Kinda useful if you are using a JDM ECU to get around the EGR requirement and don't want your top speed limited.

Not hard to figure out. Good luck with your problem.

Cubic Boron Nitride...near diamond in terms of hardness. The cutter is actually made of polycrystalline form of the material and is especially suited to machining steel. Polycrystalline Diamond (PCD) is often used to machine aluminum to the same type finish.

There is zero reason to have 2 threads going on the same subject...threads merged. Please do not do this again...bump your old thread.

Code 51 is the TPS - most likely it's out of adjustment. A code 51 will occur every time with the AC button depressed or depressing the gas pedal while reading codes. Look at the TRSM on how to adjust the TPS. In general, when you fix a code, you need to pull the EFI fuse to clear codes in...
