something I just though about on the coils... do a resistance test on them when hot. not sure what the spec is, but if you get you an old connector and cut the clip off, leave some wire length on it to use on your meter. test the resistance between and as well as to ground on each. if you...

iirc the nickle base stuff is resistant to 1000+ degrees. at work thy use some stuff like that rated to take up to 2000+ degrees. for in the head I would go that route. copper should be good too as long as it can tolerate up to 300 degrees since it's in that environment.

I know it might not be feesable to do remote mount coils on these engines but I have never liked the coils mounted over the plug holes or on the engine (heat). a fella can't really go old-school trying to find a miss! those short plug wires the last time I had to replace some, they came...

All these new vehicles out there, it be nice if they made repop parts and maybe even frames from stainless!

I can dig up which wires are which on the OPS and where you need to connect to. everyone is correct for a proper way, building a harness that is plug n play is the way to go and not cut and splice into the factory harness. the one connector that might be hard to find a female of is the OPS...

Nice photo! donno if its allowed over on reddit, but I would say if some of those folks wanna join up here in the forums for help or just to join in on the fun. most of us don't really do much in social media. I am a member there on reddit but mainly to get help with my 3d printers. there...

depending on the age and mileage on the GP's and injectors, I would also try to rule them out but also plan to replace very soon. GP's use only AC Delco. the OEM was the 9g's but we all are recommending to use the 60g's due to them not expanding in the head causing a massive "oh shit" moment...

Injectors could be the issue, but I doubt that would just suddenly appear, that would be a slow over time get worse situation. I would start off by checking fuel pressure at the IP inlet post filter. easiest and most simplest way would be to pick up a tester from the local harbor freight...

try out that app on your phone called Fuelly. it's easy to keep track and get a average over several fuel-ups. also keeps track of receipts and money spent. biggest things that change mileage are wind direction along with going up hill and down hill plus elevations. if you want to get...

I know it's a dumb question, but are your brake lights still working after the install? when I replaced mine, I somehow ruined my brake light switch and had to go through that horror again to replace it!

the longer time cranking, is it a consistent crank not trying to fire off until it just starts up or is it trying to fire up? I assume batteries are hot and it's still cranking like when you installed the PM starter. is there a service engine light on after it is running or any smoke or...

Idk why GM kept changing the design of these clips. the one on my 95 had a flat piece that clipped over the end of the shaft, you had to pry it up then slide the clip to pull off the shaft. and to do that all with one hand. there is just barely enough room to get one hand in the hole between...

wide tires will also effect mileage. I swore up and down that after I went with the all terrain tires on my 95 I lost mileage though everyone I have talked to and seen the tires says otherwise. they are wider and have heavy tread, not so much that they sing. the main thing I noticed on...

I would go with the first one. that way when the LED bulb fails you can replace and not have to replace the entire assembly. most of the LED bulbs now have little fans to help with cooling. if you go with one of the others and one goes out, now you need to replace both only because you...

most if the time with a hydroboost if your steering the wheel, the sharper you turn the less pressure you have for the brake pedal. you will also feel this in the steering wheel when pressing the pedal and then trying to turn the wheel in a quick manor. does it still stop well on a straight...

the hoses are decent from any auto parts but the pump.... if yous is leaking but still working perfectly fine, I would just get a seal kit for it. if you have to replace the pump, it will never be the same. trust me when I say most places make a "one size fits all" and junk rebuilt and...

time to pull the panel and get cut up trying to get the glass off the track just to get the wire connected!

best to check with your local DOT. if you plan to cross state lines you also need to look up the regulations in those states as well. IDK about length, but most DOT will tell you do not exceed what the sticker shows on your door. doing it commercially you will be subject to the same scrutiny...

in other news today I have been noticing the AC in the 93 not cooling as well as it has been. even though outside temps are in the mid 80's now. connected my gauges and it was a little low. added one fresh can of compressed air! first time since getting it working last summer that I have...

Disabled the OnStar, found the module under the passenger side rear seat. just removed all of the connectors and antennas. for piece of mind I got my amp clamp out and measured the amp output on the wire to the alternator, battery, and main fuse block. the alternator only pushes 26 amps at...
