96 I30 idles great, will not drive

[todddavis2000]

have a 96 I30. thats driving me crazy! It will idle perfectly, but when i rev the engine, it starts knocking, pinging, and will not go above 2000 rpm at best. It will not drive, totally unable to pull. the following are facts that led up to this problem....1. the check engine light would come on periodically, and has had a little hesitation/ missing at certain throttle positions2. started noticing a very small hissing sound3. auto zone said the CEL indicated the knock sensor and the EGR valve4. days later noticed the hissing sound was very loud, filled up at gas station5. the following day, noticed loss of power when going over mountain6. 30 miles later, was only able to go 50 mph when going over mountain7. 10 miles later, lost complete power, would idle but wouldnt pull8. discovered hose from ERG valve to vacuum modulator was busted, replaced but did not help9. replaced spark plugs. air filter and fuel filter, no luck10. replaced MAFM, no luck11. idled half the gas out of tank, replaced with fresh gas, no luck the exhaust has a smell of gas indicating its running rich. Any suggestions? Could a faulty or plugged ERG valve cause this problem???
