help! friends car wont go past 4mph!

[lookinfor10s]

Ok, so i am working on my friends car. We both have 95' tsi's. This is what he told me, it ran perfect and drove great, he came over with it running fine. Went to leave and it wont go over 4mph. Now its sitting at my house. I cant figure out whats wrong with it. Its running rediculously rich, obviously fouling out plugs like crazy, cant find a boost leak, fuel filter is fine, i just need some more ideas. Please help if you can

Well you can start by saying what the hell you guys ####ed up and we'll give you instructions on how to fix it.

plugged cat?

i didnt check the ic for holes and it already has a cel from the exhaust.

 

[BigSorn]

did you do a proper boostleak test(build a tester ect.)?

 

[pj91gsx]

if it throws a cel, after you fix all of the boost leaks, then you should go to autozone to have them check out. just dont hold up traffic and coast the hills at 4 mph

Also check around the passenger footwell over to the left if you smell a burning plastic smell it might be your ecu taking a poop on ya. just an easy thing you can check. usually when everythings fine and something suddenly goes wrong its an ecu related problem

 

[pj91gsx]

did you have the battery connect and then plug in the ecu, thats bad for it.

Is the transmission good? does it go in all gears, try running it in second. or it still wont go higher?

we need more info, or maybe post up a video to help us help you.

 

[lookinfor10s]

ok, well im out of state on business so when i get back friday and get to work on it i will fill everyone in with more info and probably post a video. Also the ecu was never disconnected so if its burning the board its doing it on its own.

 

[lookinfor10s]

also i did take it to autozone, they said they cant scan it

Try switching out your MAF. I remember when I did my first FMIC install I forgot to plug it back in, well lets say the car didn't run the same

 

[stefanOst]

Is the MAF plugged in?

 

[pj91gsx]

my brothers car was very very slow when he had a battery drain and the battery had very low voltage, can you get up to 4 then shift into second and get up to more mph?

 

[lookinfor10s]

well i just got evacuated out of my seminars in waterloo due to flooding, so i will be home tonight to do a little diagnosing and see what i can find out. Ill keep posting updates

thanks

Does your buds car sound and feel like its running on 3 cyl? If so try checking voltage at the o2 sensor ,it may send voltage but weak voltage as to not give you a cel .It happend to me on my 97 tsi, I changed front o2 sensor and the car got 1000 times better and was better on fuel. anyway good luck.

check and see if all of the spark plugs fire and make sure the plugs are on right firing order is 4123.

check and see if all of the spark plugs fire and make sure the plugs are on right firing order is 4123.

just to clear it up.

also check you cams and crank to see if they are in time.
