Re: Away from home!!, new EGR valve and a new problem

Do not squirt ovan cleaner onto aluminum!!!

Block the valve by placing a coin over both ports on topof the gasket, replace valve and do not over tighten or it will break.

Re: Any tests to determine if my MP7 transmission is slipping or not ?

There are multiple parameters that determine a shift point with the automatic and if you were accelerating at the time it will not shift as the drop to 2100 rpm will feel like you dropped an anchor...

Re: Any tests to determine if my MP7 transmission is slipping or not ?

The snapshot MPG calculator is usually close if everything else is correct. The usual 3% or so error either high or low in the speedometer is the result of the programmed tire and the installed tire....

Re: Any tests to determine if my MP7 transmission is slipping or not ?

Those are the highest gas mileage lowest acceleration tires that are OEM recommended. Your mileage is really poor, even for the area you are attempting to drive in.

Re: Any tests to determine if my MP7 transmission is slipping or not ?

If the converter is not locked it will set a code or there are serious problems with both the ECU and TCU.

Programmed tire size and actual installed tires will throw off the shift points and that...

The vent hose and funny cap confuse lots of people because then do not connect to anything so the function is not real obvious and being missing does not cause immediate problems.

Re: Any tests to determine if my MP7 transmission is slipping or not ?

The DOHC has a higher idle spec, 750 +/- 50 neutral or 775 +/- 50 a/c on and park passes for neutral. PCM allows 100 RPM error before correcting so that is only a minor indication at this point.

Re: Any tests to determine if my MP7 transmission is slipping or not ?

Silverblu02SL2: The timing advance looks OK but the RPM seems a bit high for 50 mph, are you sure it had shifted into top gear?

What size tires are on the car?

Re: Finding an alignment shot

They have camber wedges in their tool box for doing that job without any special bolts and the "camber bolt" drill is a scam and rip off. Leave that shop and report them to the local BBB etc.

Re: Replacing a flexpipe without welding

If it is a proper inspection you will fail with clamps so get it welded in and that is a metric size pipe so uou get one a to match pipe and stretch to slip over to weld.

Re: Any tests to determine if my MP7 transmission is slipping or not ?

I think Torque Pro will display it. Specifically at idle after idling for 3-4 minutes and when you accelerate from a stop to cursing speed in top gear.
