Pulling at 35-50mph....???

Anyone know why my car would be pulling around 35-50 mph? it jerks.... Started to idle really low the other day at a red light.. may have just been having a bad day... Any feed back would be nice... it's going in the shop today...

oh.. not on my sig... 134k miles

not sure what you mean by pulling at 35-50 but if it was jerking check the spark plugs. might just need a tune up.

Whoa...its been long long time since I seen that username....anyway if notthe plugs, check the wires.

i would try your fuel injecters,have them cleaned it should work if thats the problem

someone said it could be tranny? Any thoughts on that?

if the RPM's go up really quick but your not accelerating then its your tranny. Most of the time its probably your plugs or wirse. If anything i wouldnt be surprised if the seals between the valve cover and head where the spark plugs go leaked and there is oil in your plugs. takes 1 sec to check pop the hood and pull each wire out and check. if there is no oil take out your plugs and check em

i think you would know if it was the tranny,real easy to tell but that sounds like clogged injectors,try a jiffy lube they have a good injector cleaning for like 50 bucks,its a noticeable difference you should be able to tell

UPDATE:

Put it in the shop just to get em to check it out.. OMG... I've never had the air filter replaced.. AWFUL!... oh.. and it was my plugs.. back when I got the car I remembered they tried replacing them but there was one that they were afraid to pull because they didn't want to ruin the thread... (or something) and they got it out this time.. It runs so much better...

Thanks for all the help guys :)

I appreciate it :)
