I have recently bought the car listed above 2.0 SOHC. I had a friend and a fella at local parts house put on computer.Both said timing belt skipped 1 tooth and the Idle Air Control Value. We reset the light but it come right back on.The car runs great, my opinion don't think it has skipped a tooth, just runs to good. So should i tear down and replace belt an tensioner? An get new IAC valve? or maybe clean mine? An I love 2CarPros been looking on here for about 3 years now to get advice. thanks and this my first question to post. Thanks for all the help.

Good morning,

Remember, parts guys sell parts and are not technicians.

Let us start with the codes? Can you post them so I can check on the possibilities?

Okay, the 32 is for the EGR circuit. This may be a wiring issue.

The 54 is for cam sensor.

I attached the flow charts. Most of the time it is wiring that is the issues especially due to the age of the car.

Glad you did not listen to the parts guy.

The relay you removed and placed somewhere else may be the failure. Did you replace the relay with a new one?

I attached a wiring diagram of the blower motor system. Check the fuse for power on both sides.

check for voltage to the motor .

sorry about that but I have recently run into problem with the car.When I start it,,the idle is ruff and will barely rev.I have sorta wiggled the wires going to coil pack and it will pick up, but more you wiggle it get just about kill it.When idling I pull the plug loose then went to EGR an it bout went dead so I put it back real quick. My question is, should I start unraveling the tape on harness an look for loose connections?thanks again for your help.

Yes, I would. You have an issue with the harness or the connector itself.

You are welcome

I would replace the connector. They make what is called a pigtail at a parts store. Tell him your vehicle information and ask them for a pigtail. Then you just solder and shrink wrap the wires.

Unplug it after turning it off. If the noise stops, then yes, replace it.

I have recently started hearing a noise sounds like it coming from transmission. On a cold start if you put foot on brake an hold the sound starts, you put in neutral an it stops.It won't do it every time but was just wondering what it may be?? An another if defrost is on why are the fans kicking on an off?? Relay again??Thank you

As far as the transmission, I would start by changing the fluid and filter. It may be making the noise from a clogged filter.

https://www.2carpros.com/articles/how-to-service-an-automatic-transmission

As far as the defrost, The AC compressor is commanded on in defrost which means the cooling fan will operate.

yes it does, but the fans will kick on an off. is that what they are suppose to do? And that noise on transmission is like clack,clack, clack. put in neutral and it's a hard shift. could it be over filled?

Okay, I heard the noise, That is way too deep for a transmission noise. It sounds more like engine related.

The first thought is a cracked flywheel. I would have a shop double-check this and confirm. It could be a warning of something serious coming up.

the noise is not getting louder but I did seem to catch in action.Car was on operating temperature, and when given very little gas. it sounded like it was low of oil but wasn't knocking.

Recently I've noticed my windows fogging up from inside. more than likely that is heater core leaking right?? And i have noticed like the rpm's will hang little high when foot off accelerator or when driving. When I ease my foot off it the rpm's will drop,but soon as foot back on gas it jumps back up there like very sensitive?? Could the be signs of weak fuel pump??
