Feel jerk under seat area when stopped at light

Disturbing burps/ jerks which are not associated with noise when stopped at light.

Noticed as it happens the oil pressure guage moves slightly in sinc with it.

Used to have a sort of lumpiness at lights but that was differe t that was sort of a loppy idle
I have changed a cracked vac hose & connected a disconnected air inject valve but that hose is bad too so have to change that.

Not sure what to associate this sort of odd sporadic burb/ jerk & oddly felt under the seat
or perhaps is the exhaust pipes

I have scraped a severe driveway ramp a few times

Have had to have the pipes secured a bit after that as that too caused a similar strange vibration sort of thud. Thing is that was mainly at acceleration from a stop.

I will have to have the exhaust pipes checked
get new hangers & make sure all is secure

Just wondering what this could be a symptom of??????

Still have to change ign wires dis cap & rotors when they get here.
Wires really look old

Car has new radiator/thermo /rad cap as it was runining hot
now runs 90 /95 C

I added techron fuel concentrate to clean injectors & such as the car has been sitting a few years...
I am not sure if this started before that addition though.

Other than that car is smooth & responsive when driving.

Still trying to source high idle when started but thats been getting lower with use & vac fixes.
starts 1000 then as it warms it goes to 1200 to maybe 1500 then back to 900 1000 when warm in park
idles normal in drive about 650

thinking exhaust

the more I think about it
I think pipe hitting underside of car
there is no noise assiocaited w it
so something may be loose
I feel it hit bottom car

thing is O only feel it when the car is stopped at a light

Its similar to the last time a pipe was loose
Enrique tigtened something

said don't scrape anything or it will come loose again

I have to get someone to look at it

I'll pay fopr the mb hangers if needed

don't know
back to Enriques & have him install the spark plugs
or bring it into my volvo benz shop
get a 2nd opinion on things & they did a good job on the back pipe & muffler on my volvo so they can weld & things...

Guess it can't hurt
just don't want my exhaust to fall off...

Stilkl got to wait til I get my ign wires dis cap rotor & plugs in mail Monday I hope
just in time for jury duty


So this may take another week...
