Once engine has warmed up about 15 minutes of driving it will idle fine but when you give it throttle it loses power & have to keep on the gas to get anything out of it. Prior to this problem I had to replace the throttle position sensor, fuel injector gaskets, fuel filter. Any suggestions? DanD Veteran / Moderator Jan 13, 2010, 7:09 AM Post #2 of 4 (3402 views) Re: 95 Chevy G20 van loses power Sign In The basic things I can think of are possible low fuel pressure (weak fuel pump) or restricted exhaust (partly plugged converter)? You may also want to have the vehicle scanned; not so much just for codes but to compare sensor readings to known good. When other then the items you mentioned; has the vehicle been serviced, as in tuned-up?
