IAC for my 98GT?

[HipsterDoofus]

Ok, so I went to NAPA and had my CEL tested, I got two codes. One for my knock sensor, that I already knew about AND P1507.

 

So, I hit the internet, and searched the forums and such. I want to avoid dropping 250+ on my car if I dont have to. Especially seeing as I have to get my car through emissions by Friday night to go and get it registered by Saturday.

 

Now, I havent noticed any hard idling. I do notice my car doesn't like to go into 4th until almost 6k RPM...That cant be good, right?

 

I've seen a lot of people mention replacing the Neutral Safety Switch. Is this a viable option?

 

Others mention just taking the IAC Valve out and cleaning it.

 

Are these both viable options to try before dumping the money on a new IAC Valve? And if so, Is it something me, an inexperienced person with motors can do myself?

 

Is there a chance that because my car is as old as it is, that I should just say **** it and replace it?

buy a new rubber gasket and try cleaning it.

 

Wait till the car is cool to remove it. If that doesn't work troll NASIOC for a used one.

 

The transmission issue shouldn't be related. If you haven't flushed the tranny recently I'd do so.

Im going to ask a stupid question...

 

Which rubber gasket?

 

And I haven't flushed the tranny since i bought the car

the IAC has a rubber gasket that seals it. It should be less than $5.00 at any dealer.

 

 

I would do the tranny and rear diff fluid if you haven't in the last 30k.
