As I have to mention this as well , last Thursday I replaced my coolant bottle and accidently the plastic tube which connnects to the air intake got broke the one next to the strut bar and I replaced it so should this issue lead to this cause AND IS IT OK TO DRIVE THE CAR TILL I REPLACE THE SOLONOIDS AND DOES THIS LEAD TO SLOW DOWN THE CAR

Roytary

Where exactly near the strut bar have you replaced the ''plastic tube'' ? near the air pump ? Since you've worked on the car lately look for a vacuum line you might have disconnected accidentally, probbly the ssv one, it's situated under the EGR valve on the left side of the engine if you're looking at it from the front of the car.

harithac

No sir , not that, its the plastic **** near to the top of the MAF whuch connects to the throttle body , I can feel that my car is no providing the power it used to, and my friend is suggesting that P0661 is with regard to solonoids so is t ok if drive till I replace them and does this is the reson for my poor profomance.

Roytary

You mean the 90 degrees **** on top of the air intake tube right before the throttle body ? if so this breather connects right to the intake manifold near ssv, witch could give you a p0661 code, inspect the 90 degree coupler for a crack or bad seal

harithac

Yes Sir , thats the part which got broke the plastic **** that connects to the air intake tube ,
Sir is t ok to drive the car till i put it to the delaer and is this the reson my cars power have gone down

I would at least tape up that part. it will let un metered air into the intake and screw up the mixture. The computer can likely adjust, but will not be happy. If it is the one that goes to the Jet Air, it is a measurable vacuum leak. Electrical tape will do it until you get a replacement.

Check the SSV threads. They show how to reach down there and make sure the valve is still working. Although most need cleaning anyway. There is a good DIY on how to take it out and clean it. I just takes time and is dirty.

Sir like it was not broken from there when I brought the car , it was so solid and my dealer have broken the plastic **** when I went to replace my coolant bottle , and they have replaced it ,now its not solid it can be move from the hand and is t the reason that I get this code sir and is t ok to drive around till I repair this , and my RPM needle is coming down at once when I take my foot from the accilator when Im in the 4 th or 3rd gear , and I do have to mention I have lost little bit of power because I couldn't race a honda civic also even I was going 140 sir

Guys neee an opinion , I dont know wether its related to this issue , my car heats up at iddle and it get cool when moving but it wont happen all the time im confused please help me out guys

Steve Dallas

What do you mean by heats up? To what temperature? Are you monitoring your temps somehow or just relying on the dash gauge? Can you give a detailed description of what is happening?

Videos and pictures might best, your descriptions are not easy to read.

harithac

I monitor my coolant temps from the obd 2 adapter , and it gets sometimes to 226F in idle and it will go down as I start to move , but sometimes car cools down in idle , and I feel the AC is also getting low in idle .

What's the ambient temperature when you get up to 226? That's definitely not normal. Are your fans turning on?

harithac

amb temp was around 30 - my fans were on for like 2 minutes after I switched off the motor , nd itbwas pretty loud as well.

Roytary

Srry about the delay i was busy as hell, The **** we talked about could lead to missreading from ecu in relation to Maf sensor since the amount of air calculated by maf is a bit off with a leak after its position, could lead to a richer air/fuel mix but not a huge issue, richer mix could lead to power loss and its a probable cause to your problem. Heating issues on the other hand is another story not related to the first issue. Generally a overheating motor standing still witch regulate itself while moving is caused by a bad water pump ''try to rev the engine and look if the temps goes down'' , if thats the case the pump might be defective, or your radiator fan aren't working and without movement winds the radiator can't be efficient.
