Plymouth Colt Vista - Answered Questions & Fixed Issues

MAKE SURE THE MAF plug is properly connected at the air filter housing- then check the idle air control motor assy. on the throttle body.Then remove and clean your dirty EGR valve- which is stuck open and allowing EGR at idle...which is not supposed to happen...

This is the kind of question for a YouTube search.

consult a professional mechanic

The fuel filter is under the hood, in the middle of the upper firewall, mounted in fuel line.

check fuse and relay if good than pull up switch and check for power to switch also check the wire harness between door by hinge where it enters door for damage or shorts

Unless you are in a very hot climate, with no air con working the radiator fan does not normally come on.

ouch, sorry to hear that. its probably a horribly bad head gasket. although im not sure.

Frist check your fuses.

This can be caused by several different things, such as: A bad axle shaft, the differential or transaxle bearings. The ring and pinion drive, wheel bearings etc. Any one of these will cause shaking and noise on deceleration. Check transaxle fluid level, raise vehicle front end and check for slop in the wheel bearings and check for noise while spinning the tire. The wheel bearings will often make noise when lugging down as you put it due to the weight shift to the front wheels. This also applies to the axle shafts and CV joints and the differential.

Check the antifreez make sure it is not just water u can also test the antifreez to see how good it is.another reason it could be is your thermostat may need to changed or you may need one put in if someone has removed.the last thing it could be is more expensive it would be your heater core.

Pull it The relay is a plug in in the fuse box under he hood

1 may be alternator amp is low and load is high 2 alternator main +B to battery wire resistance to high

Not likely Do you not ask these questions over the years, at the shops you go to? They have the answers or the car has other issues & the parts they are using aren't good quality

165-185 temp is usually adequate..go with 185

you have a bad ignition power transistor.

Your starter is worn out and needs to be replaced.

Your fuel pump is worn out...

You have a bad ignition power transistor ( this does roughly the same function as an ignition module) or a bad ignition coil. I would bet on a bad transistor....

when you turn on the AC- the idle evens out because the ecm instructs the Idle air motor to increase the airflow into the throttle body to maintain idle speed under the increased engine load. The idle air motor is defective on your car- it does the same function as a valve but is actually a small motor...

make sure all the electrical connectors to the trans are properly connected. One of these plugs is for the shift control solenoids- not properly connected = no shifting. This happened during the repair operation which is why the car worked fine before the water pump was replaced.
