my 93 explorer shakes like the front is wobbling,my transmission was rebuilt. ijust replaced spark plugs, and o2 sensors (2 on exhaust pipe) my mpg has dropped o2 sensor didn't seem to improve my mpg. my leaf springs, rotors and pads are shot. ANY IDEAS I'M CONSIDERING RUNNING IT TO DEATH THEN GET SOMETHING ELSE. I REPLACED FUEL PUMP/ SENDING UNIT. I HAVE A PORT WHERE THE VACUUM LINES HOOK UP THAT IS JUST SUCKING///// NO LINE ON IT////VACUUMLINE DIAGRAM NOT IN REPAIR MANUEL. IDLE SEEMS KINDA ROUGH......SCAN CODE INTICATED HEGO HEATED EXHAUST GAS OXYGEN SENSOR BANK 1 AND 2 VOLTAGE INDICATES RICH. I'VE TRIED BLOCKING THE VACUUMPORT AND LETTING IT SUCK W/ NO HOSE.[/align]__________________[/align]

 

This is just tooconfusing. Are you worried about the front end shake, or how the engine runs?

 

Sounds like you need to align the front end.

 

I think it would be a kinder and gentler thing to just lead it out into the back pasture and put it down.

 

No really, the rich condition and sucking vacuum line can go together, if the line goes on the fuel pressure regulator. Again, is the vacuum line at the rear of the intake? these would swell up and blow off if the transmission modulator was leaking and the engine sucking tranny fluid. Also there are vacuum caps on that "T", there should be about 6 or 7 ports on the "T". If the cap blew off, then just replace it. But check for the presence of tranny fluid because that can ruin the O2's and spark plugs. Now, check those things and get back to us.

 

there are 7 one is a hose going to another port.one goes to a big canister beside it on the fire wall. ithink another goes to another canister looking thing.i think one or 2 go towards a/c.then the one just sucking no hose. i got a cap from a salvage yard.ithinkwhen it's capped the engine doesn't run as high. seems when i capit it does n't idle as high....or it could be viceversa.but i know it seems when it's capped the check engine comes on but that could be a coincidence.also i wasn't getting below 12 mpg but when i capped mpg dropped to 7mpg could be a coincidence as well.the codes as previously stated are hego rich....bank 1 and 2 i replced the 2 o2 sensors....and check engine came on after doing the 02 sensor w/the vacuumline capped.i took capoff sat.night nomore checkengine light.i had modulator replced w/transmission rebuild. can't locate a diagramof where vacuumlines should be going to.but i seriously doubt a hose should be coming fromone port to another port like a bypass. stillleaving one port w/ nohose on it.
