    Opinion Time: Valve Springs

    Rubie, its cheap insurance. Anytime you have access to critical wear parts when doing other work, its just as easy to reassemble with new as it is to put old stuff back together and go to bed wondering...if...when...shoulda? Besides, this is opportunity to do a little upgrade. Faster springs...

    Opinion Time: Valve Springs

    Replace. Never walk past wear parts on the way to something else. Replace wear parts as they are encountered. Springs in a motor that gets spun to redline 5 times a yr get soft. Its just as much about hot/cold cycles as it is tension/compression. A replacement/upgrade with fresh seals and...

    Code 33, MAF or burnoff relay problem?

    With the MAF its really a process of elimination. This is the one area where the FSM gets vague....and a scanner is the ONLY way to really see whats going on. Heres the deal... you can spend $250 on a scanner that will show you exactly what the MAF is doing and tell you if its a relay or the...

    cdm vs etr unity

    I'm sure that Bose/Corvette units can be traded around but the wire harness would have to be adpated. You have to work within the Bose/Vette line because of the speaker amps and the need to mate the tuner/cd to the speaker/amp system. Otherwise, the entire system has to be replaced. If you were...

    Help! replacing Doug Nash 4 + 3 with 6 sp

    Remember...the trans is as cold as anything and thicker grease cushions loose parts better....once warm it thins and the excessive play becomes more obvious. Sounds like a clutch not completely disengaging and a worn syncro. The syncros are what allow a shift from any gear to any gear without...

    Transmission downshift

    John, Take a look at the actual linkage on the trans before doing anything else... IIRC the assy is held by a couple or 3 bolts that CAN come loose and you loose gears as it loosens. I lost half my trans once before...stick felt funny so I looked underneath. Linkage flopping around so the cable...

    battery drain 1985

    Well, if you do not have a small jumper post with about 5 terminals stacked on it, behind the battery near the door jam, then you have the system that Vetteoz detailed in the drawings he posted. I can;t be of much help there since mine is so different.

    battery drain 1985

    I can't speak to which yrs or exactly when that might have changed, possible 85-86? I know my 87 has layers of protection between battery and fuses/ servos. Battery has single cable to starter. No dist from there to anything else. Red wire to jumper post where fusable link "A" then takes...

    Help! 95 vette over heats when iddling

    You need a shop with more Vette experience... The gauge gets its info off a separate sensor. The fans get turned on thru the ECM via their own sensor. This shop is throwing parts at a problem they do not understand. Has anyone verified that the shroud is clean? This sounds more like a bad...

    battery drain 1985

    Your JUMPER POST is the small stud with orange and red wires bolted to it. Just follow the batterys POS wire to the post...easy. Then follow all the wires from there..thru the links to destination. You have to remove the battery and support tray to access all the links. The jumper is supplied...

    battery drain 1985

    Your drawing is not detailing the whole elec system... half your power pathways are NOT thru the fuse panel. They run off the jumper post thru fusable links under the battery then to destination...ECM, cabin assy, engine bay, chassis...all over the car. D/C at the source, not the fuse panel.

    Muffler Eliminators a good idea?

    There are plenty of production vehicles that generate 500+ hp and as much or more torque and do not rattle the windows when they drive by. For me, thats the standard. To me, that says that the science of sound can merge with mechanical engineering. You can have power and a reasonable...

    starts then dies

    I think yours has the ESC module by the washer bottle...if it were a real 'knock' the knock sensor should retard it enough to end it..unless its already at the end of its window. Ping is caused by something that glows red hot and causes the fuel charge to ignite early...premature ignition...

    starts then dies

    The thing about temps is that what YOU see is not necessarily what the ECM is seeing. With several senders and none interconnected...you get your display off of 1 then the ecm gets info from another...so one can be bad and the other not. If you have the 2 displays...see what the difference is...

    Muffler Eliminators a good idea?

    I ran a Borla? or Corsa? I forget which...muffler eliminator and drove that for several months.. Went up the west coast and down again. At first it was fun...but after driving open hiway for hours at a time it got old.....pretty fast. When you cannot hear the stereo, or make a ph call, or even...

    starts then dies

    well....no codes says as much as having a whole list..... Pinking 'eh... sounds like something done in the Do-Da parade...:ugh :chuckle if it were lean the o2 senor(s) would be sending all kinds of error signals and setting codes.. Could the base timing have slipped? the dist turned too...

    Question: Obd 1 scanner

    Even some of the common parts are task specific and unable to be utilized elsewhere...EX: wheel speed sensors. 99% only fit a specific wheel on a specific yr model. There are a few that cross over from an '87 left rear to a 91 right front or vice versa...(just an ex not accurate) I think the...
