The throttle body is refer to as injector mouth by the local Mech. Try service the injector nozzle as well. Replace the air filter and also check the fuel pump pressure and filter. Servicing all these parts will definitely resolve ur problem.

honmusa:
since your car was working fine before the addition of the Ac definitely the culprit that will be responsible for any issue is the compressor.
Your ECU cannot sense the presence of the Ac in the power train hence fail to adjust the engine power correspondingly to accommodate the extra compressor load.
check the original compressor probably your car is supposed to use automatic compressor but manual is used instead.

OK dt was wat d poor mechanic told me he kws, he wanted to service d injector but I told him its throttle body n he said there is nothing like dt n he is 12yrs in d biz good to kw nw. My air filter is new, I will look into other areas u raised. Compliments of d season

GAZZUZZ:
There's nothing wrong with your compressor.

The idle speed valve is not allowing enough air in the intake to compensate for the extra load when the a.c is turned on. Clean the valve and ensure it moves freely by hand before re-installing.

Would have sent you pics of how to do it but I'm not in the workshop now.

he doesn't kw wat I am talking abt n he has been a mechanic for 12 yrs

Was the ac factory fitted or Kazeem fitted?

ColeworldMD:
thanks for the enlightenment. Pls I want to buy one DC Honda Accord. The dealer told me the engine & compressor are fine but the pipes are leaking. Pls how big of an issue is fixing leaking pipes or AC in general & what is the cost? It's my first car & I don't want to buy a car that will bringing too many problems. Thanks Gazzuzz

GAZZUZZ:


No dealer will sell a car with a non functional a.c because of pipes. Pipes can be welded easily and system recharged with less than 5k in some cases (shabby job but a.c will work). Deduct the price of the entire a.c system if you want to buy the car. (about 80k)

Update

I travel with this ride to and fro for d Xmas and cover abt 500km throughout d period. I avoided d ac to avoid stalling at idle but I discovered dt my car still jerks and engine light blinks at arnd 100 to 120kmper hr speed n stall thereafter sometimes or continue at other times.

I have cleaned d nozzle and injector as advised, I noticed some improvement but symptom persists.

I want to replace my fuse and relay box BC sometimes d engine fuse unhooks n I have to press it down in d box for d engine to start - d cut n join my electrician did in dt box sha n he will b dragging with me dt he can work it n no need for a change.

Mechanic advice me to change my spark plugs dt it leaks, plus all plug wire. He insists my fuel filter n pump are okay but I am persuade to change them to.

Gazzuz u guys shld advice further

Engine light blinking is a sign of a serious misfire.misfire problem ranges from weak fuel pump, cloghed up fuel filter,dirty air filter,fouled spark plugs. Bad ignition coil. Bad speed reference sensor and many more. As for your IPDM. From your explanation you have to press a particular fuse for the car to start. Take out that particular fuse and trace it with the wiring digram you have inside the cover of the IPDM. Check for burnt traces all round. Something is going on there

In all habe you bothered running a scan

I have tried to scan it but d diagnostic plug in my car seems bad as most scanners can't recognize it, am left with manual trouble shooting besides d car is 96 i guess

Yeap I press a particular fuse for my engine to start in d fuse/relay box sometimes after stalling sometimes as d fuse unhooks

mayor2013:


If I May know what type of scan tool was being used?

ogawisdom:


Can't really tell but it looked like an enlarged laptop hope this serves as clue for u to kw d type, I will be more than happy if it can b scanned, I reside in abia state

GAZZUZZ:
Ogawisdom.

Replace all sparkplugs and if there's any leaking wire replace it.
