If I had a front plate thats how I'd try to resolve the issue for now...but I;ve got Az reg thats only 1 tag.. The double side tape is a good idea..just get a good bit on the backside so the plate don;t get drug off ! I need to go look, but IIRC there is a place just inside the nose that opens...

Try getting a handful of the left side wire harness at or directly behind the valve covers where it runs from the firewall to the valve cover to distribute fuel injector plugs.... wiggle that around and restart. IF you think there is a difference, continue to move that section around gently and...

I've seen it done, but........ you can go to home depot and buy a 6-8" flat hinge and a handful of 1/4 to 1/2 machine screws. Mount the hinge on the underside of the nose about where the plate holder is...then run a few screws thru the plate and onto the hinge. This leaves the lower plate edge...

moving the inj plug won;t hurt a thing. All that does is to ID the bad cyl as far as the fuel inj...the whole bank is the same circuit. Its called "bank-fired" where all 4 on that side fire together. If you did have a bad plug or bad section of wire to #1 that would move the problem to whatever...

Odd... if you are SURE that its an intermittent spark, causing half the cyl cycles to be 'misfires' and thus fouling the plugs, then thats all it would take for me to go buy a new distributer. Comp Sales recently had small cap HEI for sale for $88...complete. Only other thing would be injector...

Has anyone looked at the inline fuel filter lately? The reg needs a new diaphram. The system needs a new filter. Possibly a new pump w/strainer. At least do the 1st two things...

yeah.... you;re wasting your time trying to diagnose an EFI engine without the very basics... Fuel, pressure and injection spark, base timing, knock sensor, ESC and dist module FSM. The Bible for a Corvette. $100 investment will save a thousand in the 1st year. Fuel pressure test gauge...

easy enough to pull suspect inj and connect to a pump and watch the spray. A wire that can be used to make contact can be used to "cycle" the injector to see if its late or slow to keep up. Unless there is damage or known cause why this one inj has failed, it causes you to replace 8. Absolutely...

vac vvvv

Thats as much a clutch problem as it is a worn tranny.

There ARE parts available. Many of the Corvette catalog stores sell tracks exchange or rebuilt and some have kits for the repair.Its been awhile but I'm sure someone still has the kits for sale. This is just as common as the headlite motor issues that plague C4s. The wound is always the...

I wish people would leave a hint when they re-engineer something and alter wiring... Whenever I do something inside a module or box, when there is a place, I will leave a stick on label that describes any alterations or repairs so the next guy< (me included) will know whats going on. I...

I understand what you're saying and for a very long time thought the same thing... what changed my mind was that fact that the C4 EGR valve is a negetive back pressure type that uses the neg pressure in the diaphram along with the spring to operate and return the plunger. the neg pressure EGRs...

Its does not matter... I'm sure they come plugged in a certain way from the factory but its just an on/off vac switch....so vac can pass either way. The orifice is the same...it does not matter which way the flow comes from..it still does the same thing. The switch is either open to allow air...

\ The only fan switch in a cyl head is the driver side at #3 that is only for the aux fan that does not come on until 238-240 degrees. The main fan on an 87 comes on from a temp sender in the intake...so if you are not getting the main fan on until 240....or not at all, you need a relay and a...

Not a big deal. Look at the metal tag on the rt side upper of the spring to get the code. Lots of different springs. This MATTERS a LOT. Its a 1 hr job. Jack car, remove end link long bolts, allow spring to hang down. Remove the 4 center mount bolts, carefully or you crack the mount. PAY...

wheres the compression supposed to do? what compression? the cyl cannot compress anything with a hole in the head...... Thats what 9:1 compression at about 180 psi sounds like escaping thru a small hole..:chuckle

is there ANY way this could have been a floor mat issue? I ask because I have done similar things that ended badly. because of my big feet, the edge of my boot caught under the brake pedal and on top of the gas pedal.... The more I stomped the brake with my left foot the more that forced the...

it doesn't take much oil to make smoke or create smell...just a wet spot will do that. Valve cover leaks are pretty common. Just a wet gasket will seep oil onto the hot exhaust and you get that smell. The speed ? The faster the engine runs the more oil is pumped into the heads. It pools there...

you'll know if that thing is really spinning 6000 rpm ! if it will....they're not really good for that under a load. As VetteOz stated, get the TV cable set right and the rest falls in place. The ONLY other thing would possibly be a shift kit thats been installed that has altered the trans...
