1999 Volvo S70 Electrical system Problems

“We have 1999 Volvo glt. During routine maintenance our mechanic noted that our electronic throttle modulator (?) needed to be replaced. He said that he has seen this problem on many 1999-2001 volvos. The clue for him was the irregular and high idle of the car. It cost approximately $1000.00 to repair. The car only has 54k miles.”

“Car began running poorly, stalling on occasion and hesitating to accelerate. Upon servicing the car, the dealer informed me that the electronic throttle body was bad and needed to be replaced. When I took it to the dealer for replacement, they cleaned it instead. I subsequently returned to have it replaced. The dealer discounted the replacement cost by the amount I had paid for the earlier cleaning.”

“99 Volvo s 70 awd has 100k is surging & stalling. After all research it seem I'm not the only one with this defect. Everyone said the ets . I think my dealer replaced it once under warranty already. Now its doing it again . Very dangerous on the highway. I tried replacing the mass air sensor . But that's not the problem. Please look into this problem . I think Volvo need to recall this part. Thanks brad.”

“I own a 1999 Volvo S70 t5. It stalls unexpectedly and at times wont even start. This is very inconvenient, especially when you have important things to do. I have spent several thousands of dollars trying to have this problem repaired. Whenever I bring it in the problem is never diagnosed and I get stuck with some other problem they think could be the problem. I would always end up with the same problem, car stalls out completely and at times wont even start. Help!!!!!!!!!!!!!!!!!!!!!”

“My 1999 Volvo S70 glt was just turned into my local dealer. The electronic throttle module is the primary suspect. Rough idle, stalling, surging at idle, bursts of overly rich fuel mix at idle. Intermittent symptoms at idle. Runs ok at freeway speeds with mild surging.”
