Runs Like in 7 Cilinders

From above post!

If it's the EGR. Remove the air filter elbow

1.- Disconect TPS and Throttle linkage from the body.
2.- Disconect the vacuum hose from EGR Valve.
3.- There are 2 bolts to unscrew holding a plate for the EGR sensor and control valve.
4.- There are 4 bolts to unscrew holding the throttle elbow against the intake manifold.
5.- Lift the elbow straigt up, watch the gasket for damage.
6.- There is a horse shoe shape passage with 3 oppenings that gets clogged with smoke.
7.- Clean the passage with a small screw driver and choke cleaner.
(Use a rag to block the intake).
8.- Use a small hose to creat vacuum on the EGR and get it open; this will help you drain de choke cleaner, and check the EGR at the same time. If the cleaner won't drain the EGR is damaged.
9.- When you feel everything it's clean and OK, Reverse for installation.

To change the EGR if it's bad, you must disconet the pipe from the exhaust and 2 bolts from the EGR to the intake manifold.

I'd like to do the same job, but I just came out from under the car and I can't even FIND the EGR! Is this supposed to be done from the top of the engine??? Can someone please explain how to get access to the EGR valve???

Also, I would first like to clean the MAF sensor. Got stuck on step 1. It's secured in with these "tamper-proof" torx screws. I checked 3 different strores in town, no-one has even heard of these! Anyone know where I can get a #20?

Thanks for any help guys!

Yes, it is done from the top. The egr is bolted to the back of the intake. You will have to move some other small stuff to get to it. It is a little like building a ship in a bottle blindfolded. If you look toward the back of your intake you will see the elbow you need to remove. Unless you are sure your egr is bad leave it alone. The clogs happen under the elbow usually

I have not clean my MAF sensor yet, I think you can spray it with choke cleaner also.

To you can get to the EGR both top and bottom.

The job that I decribed you is done from the Top.

To get to the EGR from the bottom you must raised the car on the passanger side, loose 1 of the 2 connectors on the exhaust pipe and the 2 bolts that hold the EGR to the Intake manifold.

Good luck !!!!!!!!!!

Thanks, I'll give it a go in the morning.

Would the same issue occur on a 2000 model? I get sputtering and jerking from 40 to about 55 miles per hour.

If you feel like the transmition goes from OD to 3rd back and fort.

There is a position sensor installed on the shift linkage that tells the computer the actual shift position. When it fails tent to do the up and down shifting.

Have a Trans. chop check it.

I hope this helps you.

[thebigtexan]

How expensive is the replacement of the transmission sensor?

[jesus058]

I do not know how mutch will cost, I got mine as a freebe from a transmition shop where a got my wife's Winstar fixed.

[jesus058]

I don't think will cost more than $50

[thebigtexan]

I talked to a transmission guy and he thought it could be 1 of 2 things: plug wires or the torque converter. Thoughts?

[jesus058]

Kool

Wires are around $85 bucks

Torque a lot more.

Question: Have you check the codes?

[thebigtexan]

No, he wants to drive it in the morning. He claims that the torque convertor is also a common problem.

[thebigtexan]

Can some local parts stores pull codes?
