I have the 92 SL2, and it idles way under 500 rpms, almost 300. It also stalls if I sit at a light too long. I''ve been driving this car for 3 years, and recently put $750 into a new caliper, rear tires and breaks, passenger side wheel bearing, and rear rotors. I also got an oil change for the first time not doing it myself, and then all this starts to happen. I don''t want to blame it all on the shop, but it''s just too much of a coincidence. I believe the trany is struggling a lot as well, as the check engine light comes on for about 2 mins after the car buckles and has trouble staying in gear.

It has 138k on it, going on 39. Ran fine for 3 years, up until 2 weeks ago, not even a week after the service I had to get it mobile again.

When was the last time you ran a bottle/can of throttle body cleaner through your engine ??

Man, I can''t even tell you. I''ve had the car three years myself, and I know my uncle took good care of it, but I just don''t know that. I was gonna put some Gumout in real soon, then fill the gas tank up. Would that do anything?

Thanks for the help, archer

I also wanted to ask if it''s better to park the car in neutral and start it in neutral. I started in neutral about 10 minutes ago, and it idelled at 1k rpm perfectly.

Might work, but I prefer the spray canstuff I can spray into the throat directly ... helps get rid of gunk/trash in areas where the fuel never goes ... areas where dirt can cause sticking and lousy performance

I see. Can I do this myself by getting a mat and lying under the car to find the throttle? Also, how much does these cans run?

Thanks again

Surprise! You can do this from the top side. No crawling around on the ground - unless you drop a hanger clamp or something from the air intake ductwork. Course, I am 6ft tall, so you might need a small step stool to let you reach all the way into the engine area.


Honest answer on the price is ... I dunno. Normally, I just go to the service bay support shelves and grab one ... total guess would be around $9 usd ...

Hah, sounds too good and too easy, but hell, I''ll give it a try. Thanks again for all the help, arch.

I think I found another solution, as well. The guy I brought it to says it the "lock-up converter" on the tranny. If I unplug it, it should make the car not stall and jerk. What do you think, archer?

Thanks again

Personally, I would not do that. Without the lockup working, you will waste fuel when above 45mph because the engine will be at a higher RPM than necessary ...
