What the feck have i done??
 

Somebody help pleeease! I have managed to make my car undrivable!
After getting a new intercooler fitted i was still getting limp mode when going over 70mph and a very loud squealing sound when accelerating , so i decided to take all the i/c hoses off to check that none had burst. After finding that they were all ok i put them back on and now i am getting hardly any power from the engine at all! It doesn't even rev properly ,almost as though its not getting enough fuel. When i tried to drive it i was down to 20mph trying to get up a hill. It was fine immediately before i took the hoses off ( apart from the limp mode at 70mph and the squealing noise)
I have checked all the sensor connections that are near to the hoses that i was working on but cant find anything untoward .
Anybody got any ideas ? I would be most grateful if i could get my lovely old Volvo back up and running .

what car year and model.

Sorry, should have said its a 2002 s60 d5

The only thing I can think of is that i have maybe killed the Maf by sticking a bit of blue roll paper into the housing to clean out some dust . Possible maybe that there was a spark of static or something? But im not sure that it sounds much like faulty maf symptoms . Unplugging it doesn't really make the car run any better, it just smokes more.

Thanks for your reply Tapani .
One of those Mityvac,s sure would be very handy right enough. However what gets me is that this only happened after I took the Intercooler hoses off and put them straight back on , which would suggest that i have maybe accidentally pulled off a vacuum hose or an electrical connection for a sensor or something , but i have checked and re-checked and cant find anything. The MAF is the only thing I can think of.

have you checked the MAP sensor did you take that of .the TCV near the air box and all vac pipes

Mike i have checked the TCV and vac pipes ,but the MAP sensor, where is it situated ? I cant find the damn thing for love nor money .
cheers, Stu

Am i right in saying that only models from 2003 on have MAP sensors?

its on the cam shaft cover bottom left i believe.have you checked the vac hoses from the vac pump to the TCG that is attatched at the block. .
