Raceing idle
Hi Terry
yes you are right, your previous work caused the problem.
look for a disconnected vacuum hose somewhere from/to the manifold or throttle body, do visual check first with engine off, if you didn't see any disconnected hose, start up the engine and follow the hissing noise.
Good Luck
Gear incorrect ratio
tranny code p0700 need a tranny scanner to find the problem take it to a tranny shop
2003 dodge neon my brakes are not working, i do have break fluid
If he just poured brake fluid in the system will need to be bled of air. Air, unlike liquid, is able to be compressed and accounts for the "weak" feeling in your brakes.
To bleed the brakes, you'll need two people. One person to open the bleeder screw at each wheel, and another to pump the brakes from the driver's seat. When bubbles stop coming out of the bleeder port, close it back up and move on to the next wheel. Make sure the reservoir doesn't run dry while you're doing this.
Loss of power, transmission issues
code p0700 refers to transmission control system/MIL --malfunction===causes --wiring ---TCM (1)code po740 refers to torque converter clutch (TCC) solenoid--circuit malfunction===causes--wiring--TCC solenoid--ECM/TCM (transmission control module) (again) code p0871 refers to transmission fluid pressure (TFP) sensor C -range/ performance problem==causes---wiring--poor connection--TFP sensor--ECM /TCM (yet again)code p0734 refers to gear 3 ratio (po374 is gear ratio 4) incorrect ratio===causes --wiring--TR sensor/switch--shift solenoids--transmission mechanical fault (causes are the same for po733&734) code po846 refers to transmission fluid pressure (TFP) sensor B-range/ performance problem===causes ---wiring--poor connection--TFP sensor--ECM/TCM (again). Give the clutch a miss as you still have 1st gear and if the clutch is not working you will not be going any where. Have a pressure test done on the transmission to check for internal mechanical failures (pump ). The rest are sensors are wiring connections , sensor and TCM. My bet is the TCM unit. Have it checked out. What ever you do treat any suggestion of a new transmission with a grain of salt until you are shown proof positive that you need one.
Engine revs high in park & neutral
you could have a vacum leak some where in the system that can cause high rpm,also if you have a bad tps(throttle position sensor) it can cause this type of problem.you don`t say if you have check to see what is turning on the check engine light and what code is in the computer.this should have been done and may have help to find the problem in the begining.
Oil leak
you can have to replace Gasket, bolts, o-ring in other words, replace it and buy it a kit for this section go to
www.advanceautoparts.com and get it
God bless you
Engine turns over but car won't start
run fault codes and check for cam/crank position sensor failure.. Check that the cam shaft is actually turning and that the belt is not broken. Check immobiliser for proper operation.
