Question about 1987 Toyota MR2

1 Answer

A host of problems with my '87 MR2

I got a '87 MR2 and the guy who had it before me had put an engine w/100k miles on it and everything works okay but the cooling fan relay doesn't work so i'm in the process of finding another one.

Lately, though, I've been having a problem where when the engine is all warmed up after me driving it around for 5 mins then the idle gets lower and lower and then dies. It doesn't do that when the engine is cold.

Next problem: my check engine light is on because the coolant sensor is bad so it takes me a long time to start the car up(I have to keep starting it and it'll die over and over again until it starts warming up). I took it to a mechanic who said he replaced it and when he started it he said it started up right away but then the sensor went bad again after he had it on for about 5 mins. I don't know where that sensor is to replace it and I don't want to have him replace it again because I don't want to pay for the installation.

Next problem: the motors in the lights don't work most of the time and I discovered that when I mess with the fuse box in the front trunk the lights start moving(most of the time).

I live in Washington, any suggestions on where I can find a parts place that holds 1987 MR2's for parts and such? I also need to replace the front right blinker and front right side blinker but the fender is bent. Do I just need to get a whole new fender? Or can I just bondo that up?

Looks like you have a lot of problems due to poor maintenance. look for a salvage yard around your area. get an AFM, distributor, and coil/ingiter and swap each component one at a time to identify the culprit (I suspect coil). replace all suspect vacuum hoses (again one at a time). Check engine light can be diagnosed to point out your specific problem so there should be no guess work on this. inspect wiring that connects to the coolant sensor. Also check electrical connections (potitve battery post and all chasis ground). air pockets in the cooling system also causes idling problems so make sure you bleed it completely. also inspect air/fuel filter, plugs and plug wires and distributor cap and rotor. replace as neccessary.

good luck

2006 Hyundai.... if under 100k miles, take it to the dealer, you still have a warranty. If over 100k, it could be numerous things. Starter... coil pack.... injectors... timing mechanism. Does it try to turn over?

The new timing belt jumped

no it is not. (late answer) is this a double post?

all timing belts jump,
1: every 60k miles for most. ever read the service list.
some top quality belts go bad at 100k miles. so.....????

Honda uses an "interference" engine design.
do not skip this service, or the whole engine can grenade !!!
honda quote, pasted.
However, since these engines utilize an interference design, it is highly recommended to at least inspect the timing belt at 60,000 mile (96,000 km) intervals. It is an even better idea to replace the belt at these intervals. On 1990-94 models, Honda recommends the timing belt to be replaced at 90,000 mile (144,000 km) intervals. On 1995 models, the recommended interval is 60,000 miles (96,000 km).end quote.

and if the last guy put in a POS china belt, well, you are hosed.
no name belts are junk, never ever use one,
BTW i run Gates belts.

Fuel gauge not working. 100k miles, no other

That might work. But with that many miles it would be best to replace the whole assembly. GM unit would be the best as aftermarket stuff does not seem to last very long.

.044 plug gap.
Use NGK iridium plugs as you do not have to gap them and they last 100K miles.
Most regular NGK come pre-gapped, It never hurts to check though
