Stutter Under No Boost.

[jott5555]

ok heres the problem with my buddies 90 gst.. his oil was way low so i pulled the spark plug cover and found all the oil in the plug wells...

so after a valve cover gasket, new plugs and wires everything ran PERFECT..

so today were crusein and he boost up to 12lbs, after about 10 seconds the car stated studdering like shit again..i mean just like when the plugs were covered..

so my question is this, i dont think its a boost leak because it spudders like this at idle. and also studders while being driven.. both under boost and not...

ne help is appriciated

BTW car is a 90 gst, dejon intake, turbo smart mbc at 12lbs, boost guage.. accell 8mm plug wires and bpr7es's

MAF???

 

[Staged]

You think it's the MAFS? What kind of symptoms can this cause?

 

[chaye]

I think it may be the MAF because mine did this also, and i did everything related to idle surge till i got tired and bought the MAF just for the hell of it. I installed it and boala..my car was fixed.

 

[chaye]

cause my car had the same sputtering at idle and ran like crap all the time even under boost......i bought a MAF from the junk yard and boala my car was fixed

Yes it does sound like the MAF, good luck!

Well you have new wires and plugs and if no more oil filling the spark plug holes than other possible problems could be coil packs they go bad and aren't cheap to replace with new parts.

Also might want to change out fuel filter and clean injectors.

Perhaps having an extra O2 sensor is the problem.

If the plugs were covered in oil once, they can be covered in oil again Did you check that? The valve cover gasket isn't always the problem. Sometimes it's the oil cap gasket.

ya i check all thats stuff, i thought it was a fualty injector so i did a injector test but no luck

so we did a compression test

130 130 0 145

i beleive we have a problem here... i even did a wet test and got the same results.

so other than blown rings or some narly detination what would cause this.

oh also the oil looked like it was full of glitter.
