goodmorning all i have a 96 volvo 850 turbo wagon it is my first ever volvo and my daily driver but it has started to shake on acceleration part throttle 1/2 or more my friend thinks it is missing but i dont know what she is talking about for sure. It also seems to studder,stumble or possibly miss at idle my boyfriend says he can look at it for me what should he start checking first just don't want to be left along side of the road. any help would be very appreciated thanks (knitter66)

 

hello again i went to autozone and had them plug into the car to check for codes the codes are p0172,p0133,p0422,p1310 and p0302 did not realize the light was not suppost to be on all the time they cleared the codes but told me they will proably come back soon if i do not get the car repaired or looked at i drove it about 10 miles home without the light coming on but it still seems to be stuttering when i accelerate onto the freeway what should i have my boyfriend do first i dont have alot of money for repairs at this time with the economy such as it is
