Rpm's not dropping

[lee roy]

Hi there , I am new to the forum and to dsm's

I have a 97 gts spyder , I bought the car about a month back .
The first week the alt went , so i brought it in to get rebuilt , i got the car back and with in half an hour the timing belt went on the highway
So i got the engine rebuilt and when i got it back it would not run with the maf plugged in , so i drove it home with the maf unplugged .It runs good with the maf unplugged but very rich , so today i got a working maf and plugged it in , i got it idling better than with it unplugged but when i give gas the revs don't drop sometimes any ideas , the guy i bought it off might come by and try tuning it through the dsm link this weekend .

So does anyone have an idea of what is causing this ? I have a bolt 2.0l head and a 2.4 litre block with a 14g turbo , it was running beautiful before the timing belt went


Another quick question : I had my alternator go a second time since I rebuilt it , should my alternator be just as good as new when its rebuilt ? I bought the car with the heat shield removed , I am looking at replacing it , but I was wondering if dei's titanium wrap would help lower the ambient heat being felt by the alternator if I wrap the manifold and down pipe , or would the heat shield be a better way of keeping my alty cooler ?

THANKS in advance guys , Im new to dsm's ,so enlighten me please !

Have checked to see if your throttle is sticking or if you have any vacuum leaks?

My boost controller hose wus chewed up from sumthing so i removed it , it seemed to behave a little better, as far as I can tell there are no leaks but I only have a month of turbo experience so I could be missing something .

I was looking at the turbo and and the arm that connects to what i beleive is the waste gate , this seems to be stiff and does not budge , could this be a problem ?

Also i might try a boost leak test but i have never attempted one before would this find a leak in the vac hoses ? I hear what sound like air coming from the tb area of the engine bay though .

ok i checked around today , i found there is oil by the exhaust manifold by the turbo i noticed this cause i seen a lil smoke come from there , wut should i check for leaks ? my car has next to no power and is not making the boost it should , i can barely make it to 10psi , sumtimes it won't go to 5 psi (my car ran 20 psi before the rebuild), and it seems my bov is blowing off even when there is a vaccuum, im bringing my car in to magus asap they said there busy so i have to call next friday , but i wanna try and resolve any problems i can until then , any suggestion ?

to me it looks like an alternator issue ... to bo honest im not a pro at it but i had 2 die on me same week and b4 it did die, for a while while im in nuertal and the cars is rolling the RPMs states at 1500 to 2000 rpms until the car came to a complete stop... then the rpms would idle ... ever since i bought a brand new one did it get better... and yes i killed them by accident i was driving on nothing but alternator for 150+ miles... hope something helps
