Calling Minnesota DSMers

[Underhill]

ok, 1990 GSX (thats a turbo one), 5 spd, Allways starts, cold hot whatever. I think the wires are fine now, I spread the end open a little on all of them, and they stey put. no more cel today, I stopped for gas after driving 1/2 hr, and it ran fine the rest of the way home, except it died at a light again once. It all seems to change whats happening, now I'm back to the original problem that started everything. (minor idle surge, low idle, killing when up to temp at a light. Boost is fine, about 12-13 or so. I tried checking for boost leaks, I built one of those checker things, but it didn't hold pressure, and I couldn't hear where it was comming from, gets cold in the garage. I wouldn't mind briinging it in somewhere, if they knew what the hell they were doing, besides ripping me off. Oh, I do have a datalogger, but no idea how to use it, and yes, the MAS is hacked, but it looks like they did a good job opening it up.

hey hey hey

i really like tires plus, they do probly the best job....at putting tires on.


why in the hell would you bring your car to a tire store?

that is like bringing a transmission to best buy to get it fixed.

[GREASEMONKEY]

I'd come take a look at it, Im not sure if i will be able to fix it or not but from what it sound like it should'nt be too bad.

I'll be picking up a pocketlogger in the next few days assuming I can find what I want for the price I need. You're more than welcome to swing by and borrow it.

But JUST IN CASE... is your blow-off valve recirculated to the intake?

I have a PL cable that I don't use, if you want it for relatively cheap. I have the software for it too, I'm pretty sure it'll work on a diff PDA than mine as long as you change your reg. name to mine.

Shift key and there is only 1 period at the end of a sentance.


WOW! I never thought that I would see the day that Allan corrects someone. I guess that school really is paying off.

I must agree, all of the sponsors on this site really know their sh*t!

[Kougar]

You haven't checked fuel pressure, both cold and warm, have you? They may indicate a problem as well...plus, it's always good to know you're FP on a turbo car eh?

I think it is.

[Jakey]

You think? It may be a good idea to check.

ok, from the begining, I got the car a few months ago, I was having problems w/ it killing at lights when it was up to temp, replaced the O2 sensor, Idle speed stabalizer, plugs/wires, new intake/filter, and tightened the alternator so I didn't go through any more belts.... the latest thing that I've done was the plugs/wires (Nology/NKG) and one of the wires has poped off twice at the coil, and now it runs fine from cold, but second start while hot and I get a CEL and it runs Shi**y. I've had it in to several differant places and they all say bla bla bla, give me money...or don't even want to work on it...I wouldn't mind spending money if they were going to "fix" something, but Tires Plus looked at it ($90) and said I need new plugs/wires, after I had told them I had them on order allready.

Sounds warm up related. Have you had a chance to have the CEL pulled?
By running "shitty", what do you mean exactly? Lack of power? No idle? Wandering idle? (revs up and down up and down)
The plug wires should not be popping off the coilpacks. Check the inside of the wire and make sure the metal connecter isn't expanded to much, you might not be getting a good connection. Also, like mentioned above, make sure you have no routing issues that are causing a binding issue.
I would start by having the CEL pulled. Odds are it is a nasty leak post MAS (mass airflow sensor). It could also be related to one of the warm-up circuits/systems or a failed MAS as well. Like Jakey mentioned, make sure you CBV (blow off valve is the common name for it, it should actually be functioning like a compressor bypass valve. By this I mean, make sure the outlet tube is hooked up to you intake stream before your turbocharger) is hooked up properly. Check for vacumm/boost leaks, and make sure all your wiring around your thermostat housing is intact.
Best of luck.
