ok my car is popping...one guy said it may be way to rich and another said one tooth off on distributer....what do you think?

 

Could be that "Crappy rigged up Y-pipe". If the pipe is leaking than a popping noise will result. Check for exhaust leaks.

 

well it goes away once i give it some gas so its not the y-yipe....my pipe is just welded together with all angles from straight pieces.....no bends...hehehe......what if i moved eash plug wire one over counter clockwise

 

ttt

 

ok i moved the distributer 1 notch.......still crappy.....moved anbother....moved another....finally just got out thie timing gun and and lined it up and stuff so the timing is perect.....ok so i start it up....the *** damn poppig is still there....the carb sure as hell aint likin it....but it seems to be working fine.....the popping is repetative and fairly steady at idle.....once a second or two......im getting pissed....it aint exhaust cuz you can hear it out the back exhaust...very high pitch and mettalicy back there...up front more thumpy......what is it.....it will hold a steady idle if it dont back fire....you give it gas and it is somewhat better.....but when driving it and you give it gas it just dies.....do you think it could be my distributer?.....i really hope i didnt round off another cam

 

Any moisture in the distributor cap? Bad plug wires?

 

i got old beldin wires on my car right now....my friend said he thought those had a lifetime warrenty at napa?

 

I would say an exhaust leak. Mine did that and when I fixed it the popping noise went away.

 

Benny,

Popping in the exhaust (afterfire) or the intake (backfire)?

Possibilities are:

• Broken valve spring;
• Incorrect valve/cam timing;
• Sticking, bent, or damaged valve;
• Excess carbon in a chamber;
• Excessively lean mixture;
• Vacuum leaks;
• Exhaust leaks;
• Ignition crossfire from bad cap or wires;
• Worn distributor;
• Weak ignition coil;
• Failing spark plug;
• Leaking EGR valve;
• Plug gaps too wide;
• Dirty carburetor passages;
• Water in fuel;
• Fuel filter clogged/pump failure.

That should give you a weekend's worth of things to do...

 

sweeeeeeeeet...thanks guys i managed to score new wires for free cuz of the warrenty and now she purrs like a kitten again

 

Hi Vader,

I am currently trying to tune a supercharger on my 1991 TPI TA.

I am getting popping from the exhaust.

I asked my prom programmer to make a leaner program as I thought this problem was from unburned fuel.

Is this right?

By the way I am also getting 11:1 to 12:1 wide band A/F ratios.

Thanks.
