Gslse Starting
Hello all!!!!I'm new to the forum yet I been around the block some with the GSLSE.This is my fourth GSLSE and I'm wondering if I am going to have the same starting issues with this one too?I happen to buy this one with 56,000 original miles for $600 dollars!This one still smells new inside!Currently I am not experiencing any of the flooding issues yet I am considering switching over to a racing beat intake manifold with a thunder series 500 carb.Any words of wisdom to offer a fellow rotor head would be awesome!

Wire your fuel pump with a toggle switch and cut it off before shutting the car down. Leave the car running until it dies on its own. Startup - turn on fuel pump, turn key to ON position (dont crank car), pump gas pedal once, start car. My SE hasnt had any flooding issues since I did the fuel pump mod... Now lets see some pics of this car!

You pm's me about the mileage with the camden. You could see the same as with a carbed na setup (5% less than what you have now) if you can keep your foot out of it, which I cannot. Hearing the blower is like hearing a woman moan for more, you just gotta get on her all the time.
Keep the efi, enjoy for the great design already in place. For the future, watch for a wrecked s4 or s5 and go with a TII swap.

I am looking for the overall gains of switching over to a carb setup.For instance hp and fuel economy.I drive here in colorado throughout the winter to the snowboard resorts and wish there was a way to get the reliability out of my GSLSE.The car I have now has 57,000 miles on the original engine with a stack of records from the previous owner!I have a sweet vintage ride now(my fourth SE)and figure this is a keeper.Is there reliability in the carb set up?So many people use the 2 barrel setup yet nobody talks about efficiency.I guess when your going for power there is not much care for efficiency.

Been there done that, the mod works flawlessly and solves any flooding concerns! The racing beat intake you talk about will net a small horsepower gain above 6500 rpm (okay on a new motor, but why beat a 20 year old one) at the expense of lower rpm performance & efi efficiency. Been there seen that too, waste of money.

1). Leaking injectors. Rememdy, send them out for testing and cleaning.
2). AFM defective. Either internal problem or flap door slightly bent. Remedy, replace the AFM
3). Slow crankng speed of engine. Remedy- Clean all engine grounds and replace cables as needed.
4). Bad coolant temp sensor- Remedy- replace sensor.
In all the years that I have had SE's (3 of them now)I have been able to repair the problem.
Note: The 2nd gen leading coil install takes care of the slow cranking problem. Even when my battery has been low the engine will still fire on my SE with the 2nd gen coil.
Back to the question. No you will not gain any mileage carb'd, you will in all likely hood go down.
My Se has gotten 29.1 MPG on the highway. It gets 24-26 MPG currently in the city.
Mods include. Racing beat header/presilencer, still running stock muffler.
Electric fan. 2nd gen leading coil and plugs. KN drop in replacement air filter.
I have put in a 88 N/A transmission that has a taller 5th gear.
Other than that it's stock. The injectors are brandnew, not reman, not cleaned and tested. The O'2 sensor and coolant temp sensor are new.
Forgot that I am running a ported UIM/LIM that I did.
The altitude where I am is 4200 feet.
Cold starts are alot better with FI than with carb'd, especially at higher altitudes.

[QUOTE=rx7doctor;7429429]1st for the record. The guys that are stating to install a fuel cut off switch to eliminate the possibility of flooding. I am not one to bypass a problem, meaning fix the cause of the problem. When this problem starts occuring it is caused by one of the following.
1). Leaking injectors. Rememdy, send them out for testing and cleaning.
2). AFM defective. Either internal problem or flap door slightly bent. Remedy, replace the AFM
3). Slow crankng speed of engine. Remedy- Clean all engine grounds and replace cables as needed.
4). Bad coolant temp sensor- Remedy- replace sensor.

Sure is nice to talk to people who have an idea of whats going on with these cars!Thanks!How much were those injectors?I found them here in town from checker for 600 new!The only other option was the dealer and they wanted 1200 for new ones!You also said 2nd gen leading coil and plugs?So I can install 2nd gen plugs into my 6port?I'm sure there is a thread for switching to the 2nd gen coils in the archive section however I have heard that doing this fries the igniters.Is this true?I have to clean the upper and lower manifolds.How would I port the upper and lower sections as far as specs?

The changes in altitude you will experience getting to the slopes will kill the tuning on a carb and you'll end up holding up traffic. Unless you plan on rejetting each way on your trips. Keep the efi. I never have a problem at altuitude with my 2nd gen, the carbed 1st gen when it had the Mikuni was another matter entirely.
As for injectors, they can be sent out and cleaned for 15-30 bucks each, or bought used in good condition on the forum for 50-100 each.

2nd gen plugs work well in the leading side with the leading 2nd gen coil mod. The procedure is in the archives and only takes 15-20 minutes. They don't fry ignitors if you do the mod correctly and make sure that you put fresh thermal paste on the backs of the ignitors.
There are no specs on porting intake manifolds. You need to do a search and find someone that has posted pictures for reference.
