Cutout under the backseat worked awesome for me! My pump died at the gas station ( how ironic). Chopped a hole in the center of the backseat and there it was! Took 20 minutes with a Cutout tool. Be careful not to chop the fuel lines
Oops yeah I forgot the background. At first the car was surging at idle and had horrible gas mileage. I replaced the IAC and gave it a thorough tune up. I stumbled on what appeared to be the problem. I unplugged the vacuum for the secondary vacuum switch (attached on the back of the rear intake...
I've isolated the problem to the secondary vacuum switch. I replaced it with a new one but the car runs better with open vacuum. What gives?

Thanks to all you guys who helped try to find the prob with my SHO. I recently started hunting down vacuum leaks and disconnected some hose on the back of the rear intake. The car ran better! It is attached to a vacuum switch which has a round canister attached to one end. Anyone know what...
Got a new set of codes. 11 for no trouble and 41 rear bank lean. Runs a **** of a lot better with the wires and plugs but still consuming lots of gas. Damn hood release handle broke off too. What a string of bad luck. Gonna try another idle control valve since the one rock auto sent was a return...
Put a new MAF sensor and MAP sensor in to no luck. Wires are bad so I got those ordered with autolite double platinum plugs. I'll hose down the butterfly as well . I suppose if I keep replacing stuff I'll eventually get it lol. Thanks for the suggestions and I'm trying each one. I do have a new...
eric i'm in northwest indiana near gary. the codes are in my first post {2 digit eec-iv}. with the gas it runs fine but if you let off it surges or dies outright. shotimes says it may be the MAF sensor and that just might sound right since those things usually crap out in freezing weather. i...
I checked and found out it was a old hose that was replaced already. It went from the throttle body to the cruise control area. It's hesitating on acceleration and is starting to run rough at start up. I got some nasty blue smoke this morning. CPS bad? Frickin water pump is slow to turn when...
Well I've looked and I need a hand here.
My 91 SHO will not idle and will sputter and die as soon as the clutch is pushed in. At start up it will run smooth for 20 seconds and then it starts surging and will eventually die out. The key test gives me codes 24, 41, and 91. The run test gives me...
