Very low idle and dimming lights, Celica had a heart attack ?? Options

[Remy]

Hey all, this morning I was driving to work on the highway and as I was approaching my exit this truck started tailgating me I was like wtf ? So I switched lane and he followed me as I got close to my exit he was still right behind me so I down shifted and took the exit and lost him as I approached the stop lights and coming to a stop my car started idling down to 150-200 and my lights and interior starts to dim down really low I though the car was gonna die on me, it was a good thing my work place was just down the block.

So I got to work and turned the car off and went inside, after I got off of work I started the car and it ran just fine drove it home (took the small street though). At first I though the alternator died on me or was going out but I drove it home after work just fine no problems at all and good idle too...? My other though was maybe its the IAC/ISC that was dirty but why would it effect my car only on the highway when I drive 60-70mph ?? If it was the IAC/ISC then it should effect my normal driving on the streets too right ?? And my idle would be high/low too ?? Anyways post up what you guys think the problem could be.....

Oh and the car just recently got seafoamed through the intake manifold only.

No one ?? Anybody know where I can get the gasket that goes between TB and Intake manifold ?? Called my local auto stores and they didn't know what I was talking about...

Is this it? http://info.rockauto.com/Fel-Pro/Detail.html?60687_TOP.jpg

$1.73 if it is... wouldn't there be one gasket in the TB itself like 2 parts to a throttle body and mating them together is one gasket and then there is the other gasket mating the throttle body to the intake mani...right? Or is there only one gasket for the celicas? My eagle talon had two like I explained above.

I found it on rockauto.com by the way...just wait for the catalogue to upload then select your make, model, year, fuel/air etc etc...

I'm not sure if theirs 2 gaskets on the TB but thats what I needed thanks !!

Check your ground wire from the amp to the chasis - you can read a whole thread of mine in the FI section on the effects this one little $5 wire can make Mine was acting like that at one point so maybe?

Nah, it's totally your alternator. It's gonna die. You're probably running on battery juice.

My alternator doesn't have a ground wire directly on it though it is grounded will it matter ?? My ground wire is connected to the engine hanger and it splits the ground with the alty and the rest of engine.

That was my first though because I've been around a couple of cars with a bad alty and my car was running exactly like that. I got my alternator tested and they said it was still good though.

Have your battery checked also.

^exactly. And keep an eye on them both. Alternator can test out fine today, but take a giant crap-o in a week. Just be safe.

My battery is still good I have a battery charger at home and it can't even charged because the batts still fully charged lol my alternator looks fine hopefully it won't go out on me. I'm gonna get the IAC clean and see if that helps. I get bad idle when I drive 60-70 and when I come to a stop going that fast too. All my grounds looks secure too new grounds btw not oem ground wires. I'm staying away from the highway for now I guess...
