Pls help, I just noticed that my camry 98 Jerks when ever the gear is engaged. Sometimes I became scared whenever I am on a hold up cos it be behaving like the engine is going to stall. It gets worse when the Ac is on. What could be the problem. Have bought injector treatment to clean the injector but problem persists. Please help.

It gets worse when the AC is on because there is more "stress" on the engine/system. Some questions:

1. When was the last time you did regular maintenance i.e. change spark plugs, change wire etc on the vehicle?
2. Any check engine light on?
3. 4 or 6 cylinder and with how many miles?

It is a 4 cylinder and it has 196,000 miles to its credit. Have not changed plug and wires for some time now though I change the oil regularly.

When you say some time, how long? Also, is the check engine light on? For issues like yours - or anyone for that matter, you want to start with the basics.

What code is it showing?

Not scanned yet. Don't know where I can get a good scan center in Asaba. Anyone with an idea??

If it jerks when gear is engaged I.e. from Park to Reverse or Drive, your engine mounts may be damaged. For that stalling, appears as air-fuel metering issue. It could be MAF sensor, fuel pump, injectors. Give it a good scan, it becomes easier to deal with.

Just back from the workshop. Plug wires were changed to a new one. Plugs were changed also. Engine is running smoothly again even with the Ac. Thanks for your contributions.
