1998 Mustang GT Problem Diagnosis Here you go Guys

[Get E Up 98]

UPDATE!
2nd Cat. on Drivers side is completely stopped up....took $60 to figure that out. So what do you guys suggest? I have heard offroad x/h pipes.....but shoot they told me $2200 to fix it at the dealer...so....guys anything....thanks for all your help guys I appreciate it..






So what do you think may be the problem....maybea vacuum problem within the EVR sensor or something....iif i bypass it it seems to run ok..a little crappy but when i give it gas it doesnt pop the hoses off. Although im sure I'll find out tomorrow whats really wrong with it just wanted to see if yall could figure it out with the sypnosis I have given you..its a tough one...and has even baffled some pretty reliable mechanics....only the diaognostic test will tell....

You can get hi-flo H-pipes with cats.

I have the MAC O/R H-pipe and I love it. Its not street legal since you will have no cats then but the sound and performance gains are awesome.
