Just joined today so hello I'm nova1274.
anyways I tried searching the forum and couldn't find anything specific to my issue so I'll be making this new topic.
My 05 STR had an issue after doing the valley hose.
Every time I take the car for a drive the car hesitates to a top speed of around 70mph. Can't shift any further and stutters, even went into limp mode for a few seconds trying to overdo it. 70mph is pretty much the top speed fyi.
some group friends on Facebook suggested possible fuel pump.
Scanner shows Throttle at low range with ignition on (no peddle )and at 100% when peddle fully pressed down.
14% with car running and revving to the limiter around 4k rpm.
Around 55 psi fuel pressure while driving. And same when driving at full throttle even though I got up to 60psi at full throttle the other day.
Any help would be great because those fuel pumps are expensive.
I found just the motor replacement but they aren't compatible with the R models so I don't know which part number goes with the R in that case.

Welcome Nova 1274, Best post this in the S Type forum, with more details. Mileage etc..

Was it running OK before you changed the valley pipe.?

Scanner shows Throttle at low range with ignition on (no peddle )and at 100% when peddle fully pressed down. ???

Have you reset the throttle range. Ignition on, (engine not running) Press accelerator to the floor, all the way down and then back to closed.(accelerator off). see the thread below.

Could be, Lack of fuel, (change the fuel filter under the wheel liner LHS) Lack of air, Blocked exhaust, (Cat damaged blocked breaking down causing a restriction) Lack of spark.
Are you getting any codes? If it went into limp mode you must have flagged something?
Could be many things.

Any sounds from the engine bay supercharger air leakage type noises??.

Have a check around and post in the S type section, A Problem shared is a Problem Halved.

 

Hello and thanks. Is it possible for you to move the post?
I'm trying not to copy and paste everything and lose your comment.
It has 93k miles and honestly when the tire truck brought it to my house a couple years ago it went right to the backyard.
And honestly I did bunch of maintenance while I had it apart.
New hoses, gaskets, spark plugs, fuel filter, oil change.
The throttle body relearn I read today for the first time when I joined.
The super charger after doing the expensive pulley upgrade and bearings and solid coupler sounds ok while driving but in idle it sounds scratchy, marbles in a can etc.

Sorry I can't move posts.

If I understand you correctly. This was a non runner delivered to your door?
You have done a supercharger overhaul, smaller pulley, bearings and solid coupler. But still sounds noisy at Idle.
and carried out a full service. ( would include a rear diff oil change, and a transmission oil and filter change but lets get it running first)

Can you read any codes?

You may have had an issue with it before you overhauled it. Like the catalytic converters breaking down and causing partial blockage at higher engine loads.

Rewrite your post, with the facts. from the above and post in the S type forum.

I understand in the states you can get the codes read at the auto stores free of charge. This would give a better idea and direction.

Along the lines of.

I bought a none runner STR 93K miles, serviced it and changed the valley pipe, and overhauled the supercharger bearing, isolated and smaller pulley when out.
Now runs and stutters at max 70mph at full load, and the supercharger is a little noisy at idle.
I have fuel pressures of ???
I get the following ???? codes stored.
I am in XYZ ( in case anyone is near by, and can recommended parts, or good independents in the area)

From the above info we may be able to help you progress the fault finding testing, checking without throwing expensive parts at it.

It sounds good and with a little more info (codes ) I am sure the forum can direct you in the correct direction.
