ProwlerGT's 3000GT Revival Thread - Start Up

[ProwlerGT]

Also, successive restarts of the car from INITIAL startup after COLD engine yields the car stalling flat out. I can baby it up with the accelerator and if I EASE the accelerator back down I can manage to get the car to stay idle. I let it stay idle revving it a few times to see if it would hold idle and it was doing so at about 750 - 800 rpm, put it in gear with brakes on and it held idle, let it warm up for 10 minutes. Turned it off and tried to restart it and it DIED. Just flat out stalled and it will not stay idle again unless I REV high again and ease her back down.

Went to go to the pressure test tonight before putting on new/used throttle body to test for FIAV being broke, but forgot that my air compressor for all my air tools is out of commission. I'm not taking apart the throttle body until I can do a proper vac leak test.... and I'm gonna do one while COLD and one while HOT. My HOPES is that the vac leak test while the engine is still hot will reveal a leak at the throttle body FIAV or else I might shoot myself.

Bought new air compressor tonight at Wal-Mart. Its a Briggs & Stratton brand which I do believe is a good brand so hopefully this one will last me more than about 20 uses like the last one from Target did.

Motivation - I gotta admit to all my fans (lol - over 6000 views in this thread) that I'm losing motivation to go into the garage and finish. Too much dead end crap is really starting to get to me and while I have improved a lot on the car and fixed a lot of issues that were obviously bad those things still did not fix the idle issue. If I go to replace the throttle body and the damn idle issue isn't resolved I might throw something through a window. Again though before I fix the idle issue I need to do a vac leak test while COLD and one while HOT and see if I get anything. I'm gonna pump it up to 17 psi and see what happens.

If anyone is handy with fixing Air Compressors (for air tool use) I'll sell ya the old one for a decent price. It is in great shape and I believe the reason it won't kick on is a simple electrical problem that I just don't have the knowledge to fix. I certainly do not believe the motor is burnt out.

[ProwlerGT]

Gave the old air compressor to an electric motor fix-it shop. They said it was cheap and useless; not worth fixing.

Have not unboxed new air compressor yet cause I figured out why I'm lacking in motivation. I'm sick . Sometimes cause I stay sick daily with chronic sinusitis I don't notice that I'm sick cause its so normal. That f'in sucks aye? Thats my life. I've been sick actually the entire 3 months I've been back home since late May. 2 antibiotics later and the good ole chemical plant air of SE Louisiana is still keeping me down.

Anyway, when I get my ass in gear i'm gonna plop my homemade plunger vac test thingy onto my air intake and vac leak test before the MAF.

Motivation:
I dug out me ole packed away PS2 and played Midnight Club II yesterday and I think it got me a lil more pumped up to go deal with the 100 degree heat we're still having here and go fiddle with the car. So progress so far today was getting the new air compressor put together per instructions, did a prestart run of it like it said, took off the air intake pipe to get ready to do a vac test. Fiddled a bit and found my air intake filter mount plate (to hold the 360 filter off the frame off the car) and come to find out it really doesn't fit right to my further disappointment. Luckily though the top plate DOES fit right. I think the plate is designed for the VR4's cause according to the picture on 3SX's web site it will not fit where the metal stud pokes out on my NA.

Hey man remember how i was having problems with my Vav booster? i figured out the problem, but only after i had won a complete brake master cylinder and vacuum booster off ebay for 50 bucks. You wanna grab it? might fix your problem.

[ProwlerGT]

I appreciate it. I have replaced the booster with a known good one and now I am pretty confident too that my old booster was still good. My MC has been completely rebuilt too with all new parts. Thanks anyway !

Yesterday I went into the garage to do a vac leak test(s) and after a couple hours of fiddling and trying to get good seals on my compressor line setup with tight electrical tape and/or duct tape I was absolutely furious that it just wasn't happening. I put a heavy duty trash bag in my intake pipe where it meets the tb and tightened it all up and then vac tested from the booster inlet and between the air noise being made at the compressor and the air noise leaking out of where the garbage bag was i wasn't able to determine any air leaks from anywhere else. Finally I took all that off and duct taped up the tb itself. I was using the air gun plugged into a hose into the booster inlet. Eventually the air forced out of where the air gun met with the hose and after I taped that off too it forced out of the duct taped tb intake area. I felt like this was good enough to tell that I don't have any leaks cause every time I was able to hear air come out it did come out of where I'd taped things up for testing. I even frayed apart a piece of nylon string and placed it at various prone leakage spots on the tb when i'd do the test to see if it would move and it didn't at all (and I wasn't holding the string so my own movements wouldn't disturb the test). I guess after having written about this I see "some" progress here, but after a couple hours fiddling yesterday and not being able to get a good seal for the pressure to hold I was extremely pissed about all the wasted time on something so simple and no progress.

Thinking still that my issue is in fact the FIAV I do have an extra TB that I bought used, but in my fury of lost patience yesterday I looked at this extra TB more closely and I feel the one I have on the car already is in better shape besides the FIAV itself. I already know my current IAC is good and I've tested my TPS to be good too, so I think I'm going to send my extra TB in to get rebuilt and machined (bored out 3mm more to 63mm too). This way I'll know for sure that I have a new and in good shape TB with a new FIAV which I will then rule out immediately on installation. I'm iffy on installing the used one as it is now cause I really don't know what that buys me and at this point I want some assurance before I do any further work on the car. The place I'm getting my TB rebuilt at is www.throttlebodys.com. The guy's work looks great from the pics.

[ProwlerGT]

Could there be a light at the end of the tunnel? I sent my throttlebody to that guy I said I would in the thread above and he said that he's pretty confident there was an air leak in it cause one of the seals was all hardened up. I am hoping after all this damn time that this will be the smoking gun. He's USPS'ing it back to me tomorrow. I cannot f'ing WAIT to install it !!!!!!

Mind you I have not been able to determine through my own vac leak testing that any leaks were coming from the TB before, but I take this guy's word for it cause he's been a machinist for 25+ years and rebuilding TB's for 10.

after you finish your car, drive to lafayette and tell me why mine is still overheating....
