Car Hesitating When I try to Accelerate
I have a 1994 Lexus LS 400 with 242,900 miles on it and the car keeps hesitating when I try to accelerate. It will get up to speed if I barely press the pedal, but I'm afraid to even pull out in traffic going 15 mph! I have changed the plugs and wires, tried fuel injection cleaner, cleaned the MAF Sensor, I don't know what to do can someone please help me out!

no cel codes, check engine flashes on then goes back off and doesn't store any codes. The spark plugs were burned pretty clean. I think i'm going to try the coil packs next. I found a vaccuum leak going to repair that today and if that doesn't do it im trying the coils next.

The RPM is supposed to be at 600 give or take 50. What happens if you have it in Park and slam the gas? Does the RPM go up or stop at a certain point, such as 2500? I think you should check the coils, starting with the driver's side.

driving it acts like it doesn't have any power. I ordered a new coil for the driver's side. I'm gonna see if that works.

Update on my lex I put in the drivers side coil and no change at all. I cleaned the MAF gonna try the throttle body this weekend and replace the other coil I guess. Any suggestions?

I once cleaned my MAF and posted about it and several people said that the MAF on the 1st gens shouldn't be cleaned and that cleaning it could ruin it. Mine was fine after the clean but there may be something wrong with your MAF because it can cause these symptoms. I would expect I to cause a CEL though.
