Took van in for tune up. Called me and said computer was bad need to replace. What is the cost of replacing it.

Provly didnt need turbo replaced just fixed..send issue to [email protected]. Hes an xpert n tell u for free

Possible results are , increased fuel use, reduction in power and you may fail noise emissions (too much noise), some after market exhaust systems are designed to give improvements but these are general much more costly than standard fittings. I would not be happy myself and would want it put right, Not sure which country you are in so can't advise on trading standards, but in uk items must be fit for purpose or you get your money back.

replace the ECM. if all else is testing fine,then the ECM is bad. this is commonly called a "brainbox",and they do go bad,sometimes all of a sudden,and 99% of th tie there is no warning. very easy to install...about 5 mins. and cost less than 150 bucks.

Check all vacuum sources for a leak. I wouldn't race engine over 3000 without a load on it.

theres a heated o2 sensor before the cat that probably needs to be replaced.this tells the computer wether the gat is flowing properly.

on that engine it is a belt newer vw's all have belts, and yes it is recomended at 100,000 miles. to do that job is a lot of work if i were to do it it be between $1,000.00 to $1,500.00

There seem to be 4 sensors along the way in the air intake and emissions system.

My Check Engine light indicated a bad sensor 1, bank 2 code (I think).

I had my mechanic replace the sensor that was indicated as faulty... cost = $191.

Then the Check Engine light came on again (with a different code), and I had to leave the van with him all day.

Cost to replace and install that sensor = $115.

My advice: if the Check Engine light stays on *AND* your vehicle is riding rough, get it fixed.

Otherwise, put a piece of tape over that Check Engine light and save a couple hundred dollars!

Hope this helps, I do trust my mechanic fully.

I have a 1986 Chevry Astro Van that I learned abot the hard way that was doing what yours is doing. In my case, after being ripped off by one fast buck mechanic after another, i learned it is the oil pump computer that probably needs to be replaced. If it does not read the right oil pressure, it won't start. But, what myinsance mechanic did was to run a wire from the ignition to the starter, etc. Cost was $11.--/ after he first pt in a starter, fuel pump, new main engine compter, etc, none of this helped it start. Then he did the hot wire thing, bypassing the oil pump computer. I undersatnd that compter is about $65.00. I got ripped off to the tune of 1,000.00 befoer thru trial and error the real cause was discovered.

Tried a new gas cap?

I just changed the rear spark plugs on my 1997 Chrysler Town & Country this weekend. It took me about 7 hours to do everything. When you replace the rear spark plugs, its a good item to replace everything i have listed below. Listed below are the items i changed while i was in there:

Valve Cover Gaskets
All 6 sparks (the rear are the hardest) I used the Bosch Plat. +4
Intake manifold gasket (only cost $3-4)
Throttle body gasket.
Air filter
Spark Plug Wires

I also bought some throttle body cleaner and sprayed the throttle body to clean it out. When the throttle body is dirty your van can stall.
I took pictures of everything i took apart, which i can email you to help you out.

Thank You,
Nip
