MAF, TPS, or O2 Sensor

Asked by Sep 24, 2016 at 08:02 PM about the 2002 Volvo S60 2.4T Turbo

Question type: Maintenance & Repair

So i bought a 2002 volvo s60 2.4 L turbo just recently. It drove home ok, but i
went to take it out and it gets half way down the road when it starts acting
weird.

At first, the car would stop all acceleration and begin this jumping/revving of
the engine. I got out of the car and notice the MAF sensor was unplugged, so
i plugged it back up and the car ran fine for about 60 miles. It then began to
do it again, along with a really slow acceleration (and i mean, i had to press
the pedal all the way down to get it to even get up to 3000 rpms). I replaced
the MAF sensor yesterday and hard reset the codes, and again the car ran
good for about 60 miles before it started again. All i have to do to get it going
again is stop the car for about 3 minutes and restart it.

Now it is worse, as it has a hard delay when accelerating, and its loud
whenever it does. it also doesn't accelerate like it should. I start the car, and it
will cut right back off if i dont give it gas. but when i do give it gas it jerks really
badly. It also will stall randomly, and i will not be able to accelerate at all. And
on 2 rare occasions, it feels like im pressing on the break whenever im not.

Im thinking maybe O2 sensor or the trottle position sensor, but im not entirely
sure and i dont want to go and spend the money for it to not be the problem.
All opinions are welcome

Test spark plugs & Plug wire. Air filter dirty can also set a MAF code along with dirty throttle body and IACV or similar VW may call it something else but Idle air control, Check for vacuum leaks, make sure all other electrical connections are good and check all fuses under dash & hood.

All the above either needs tested, cleaned and re tested and/or replaced if bad. do not throw parts at it, learn all test or cleaning procedures first and do so if its good then continue on to the main issue and if its a cat this will or should be the last to replace as it runs good until warm which can also be a symptom of a bad cat but test all other first.

So i replaced the o2 sensor, and the car seems to be running better. But it still, on occasion, idle funny whenever im in park or when i come to a stop. Also, there seems to be a lag in the transmission, because the car feels like its being pushed back. Not sure if its the transmission or not. Its now reading 2 transmission codes, as to where before it was reading 2 tran codes, along with the maf and o2 codes. The check engine light is still on

Also, these cars are known for their bad electronic throttle module (throttle body)
